power windows Grand Cherokee

Showing 2 out of 2 Posts
Question From Guest on power windows Grand Cherokee

For the 5th time, my powerwindows in my 2000 Grand Cherokee Jeep will not work. This is expensive. Is there something I can try to do to fix it? I need to get the window up, but don't want to plop down another $500!!

Response From jpgirl5587 Top Rated Answer

My suggestion to try is to check on the window motor wires on the hot side for voltage if voltage is present you have a ground problem easiest solution is to cut the ground wire splice in a new wire and ground out on window motor where it bolts to the door then window should work. Now if no voltage is present look for fuses or relays. If fuses and relays are in good order trace down wire from the fuse or relay back to the window motor and look for either broken or exposed wires grounding out. Hope this helps.

2002 Jeep Liberty Power Window Finiky

Question From merisey on 2002 Jeep Liberty Power Window Finiky

Ok looking for a little help.
My wife told me today that her window will not go up. And after interogating (sp) her I found that it had happened before and she would slam the door then it would go up... This time it didn't work. But as I toor the door apart I noticed that as it happened if I would unplug and plug the motor back in it would work again. All of the viewable wiring seems to be tight and free of corrosion. I guess my question is is the window motor just crapping out or could it be something else. When it does not work the motor makes no sound. and that I noticed sounds a little labored before the stop happens. Also it does not just stop in movement... push switch works release then not work.... checked the switch all seems well there to as far as connections go

Response From Loren Champlain Sr Top Rated Answer

You'll need to check power to the motor at the time it is inoperative. The symptoms could be the motor or the switch.

Response From VeeDub

The motor is getting a "dead" spot. When you slam the car door its like hitting that old car

02 Liberty, Battery not charging

Showing 7 out of 10 Posts | Show 3 Hidden Posts
Question From crackerjax on 02 Liberty, Battery not charging

2002 Jeep Liberty Limited (3.7L), about 120k miles

My history with this car is a lot of problems in the last year (got after the wife totaled her Accord). All windows motors dead, totally replaced power steering system 2 weeks ago, knowing there was a possible power issue.

Car is frequently dead. It would attempt to turn over. I've been able to jump with a Duracell portable battery thing and it ran well until it needed to be jumped on next start. A week later it was back to normal operation.

Last week it would not turn over (new problem). Portable battery device would start it but it would stall 2 seconds after starting, second battery connected or no. Keep foot on accelerator and it does not stall. Took main battery in, tested as bad cell, replaced, starts fine.

Checked at AutoZone with new battery installed (thinking I had either an alternator or PCM problem) and their battery tester said the battery was not being charged. Removed alternator and tested it on their bench. Alternator tests as OK.

My thought is the problem is the voltage regulator is broken. This is part of the PCM on this car. I should be able to complete that fix for under $300 (parts+install and reprogram at dealer) but...

what else could it be? The dealer will warranty their $550 PCM to fix the problem or I can get my own for $150. Install is $100-150. I need to know this is the problem.

TL;DR Battery not being charged, new battery, alternator tests good. Voltage regulator in PCM bad?

Response From Discretesignals

You need to make some electrical checks to determine what your problem is. You also may need a high end scan tool to see if the PCM is commanding the alternator or not.

With the engine running what is the battery voltage using a digital volt meter? What is the voltage at the alternator lug?

Response From crackerjax Top Rated Answer

Sorry, I haven't had a minute of daylight off since I made my post. Then it was raining when I got off work this morning. Rain abated...

about 14v in both cases. To be specific, -13.8v more or less from red (+?) to black on the battery. Battery red to a big metal bolt on the fame. Alternator lug to frame bolt. Alternator lug to black on battery.

A side note and idea... could the grounding strap have anything to do with this? I read mention on the eautorepair.net guide but there is no stated location so I cannot confirm or deny that it is attached or worn out.

Also, car works with new battery but no idea when it will stop since I've been told it is not charging. If I don't run the A/C or radio, how long you think it will run without a recharge? I'm borrowing a '93 Silverado and its eating up gas.

Response From Discretesignals

If your getting around 14 V, the alternator is operating. Take a measurement with everything turned on in the vehicle (lights, blower, heated defrosters, etc.)

If you suspect a ground strap issue, take your red meter lead and connect it to the alternator case and the black lead to the negative battery terminal with the engine running. If your meter shows 0.5V or less, you have a good ground.

Response From crackerjax

0.04v between alternator casing and negative on battery.

Alternator at minimal load is 13.9. Max load 13.7
Battery at minimal load is 13.7. Max load 13.0 and falling. 0.1v per 10 seconds. Didn't matter if I had my ground as a bolt or the battery negative.

It may be possible that the problem is intermittent. I have a 12v battery charger if needed, but could it help to run down the battery (still be able to jump it) and see if the alternator will recharge now?

Response From Discretesignals

As long as the bolt has a good path to to the battery negative, you can do that. Most techs connect to the battery terminal because you know that is the best ground to use for a reference.

It isn't unusual for some charging systems with all accessories turned on, as the engine is idling for a long period of time, for the battery voltage to drop to 12.6V or even lower. If you bring the rpm up, the voltage should come back up. This is more common on vehicles with loads of electrical accessories.

It could be intermittent charging system failure, but you have to catch it. You could also have excessive draw on the battery when the vehicle sits over night. If you have something drawing more than .050 A with the vehicle turned off, that will cause a no crank because of a discharged battery.

Response From crackerjax

The very odd thing is expecting I have a totally dead battery and I jump the car it should run. My issue was after the car was jumped it would stall within 2 seconds.

I guess I can try it with this new battery for a while and see if the car dies again.
I expect the time will come when it will not start but will run (after a jump) before it won't start and won't run (after a jump) so I can use it until it won't start. When I have to jump it I know the battery still isn't being charged. And move to the next idea.

Response From Discretesignals

The funny thing about computers in cars is that when the battery voltage gets too low, the keep alive memory gets erased. Odd things may happen when you restore power and get the engine running. The computer in your Jeep learns how to properly idle the engine and stores that information in memory, so when memory is erased it has to relearn again. During that process the engine may stall or run funny.

edit: HT beat me to it

Response From crackerjax

Interesting idea. I replaced my Ford Fusion battery and the navigation/radio acted crazy until the dealer "reset" it.

Thank you both for the prompt and understandable replies. I'll try driving it around and keeping the portable battery and voltage tester with me in case it dies again.

Response From Hammer Time

My issue was after the car was jumped it would stall within 2 seconds.

It might be having to relearn the idle strategy every time.

Question From Logan Savage on Jeep Liberty 3.7 V6 Engine

Hello all , I'm new , just found this forum & this is my first post . I'm considering doing a backyard , shade-tree parts swap & would like to know what people think . I know professional mechanics will laugh or frown at what I'm considering .
I just bought two jeep liberty's , a 2005 & a 2002 . Both have 3.7 V6's & both have great bodies & both have engine problems . The 2005 has a little over 200,000 miles on it but runs quiet with no unusual engine noises & no exhaust smoke but needs heads / valves reworked . I plan to sell it or give it to a family member after I get it running good . The 2002 has 139,000 miles on it & just had the heads reworked but has a rod knocking . I plan to keep this one & buy a good used low mileage engine for it .
Now to the jack-leg shade-tree part . I'm considering pulling the high mileage engine out of the 2005 , installing new rod & main bearings , new oil seals , new freeze plugs & a new front transmission seal , slapping the good heads off the 2002 on it & reinstalling it in the 05 . My main concern is if I'm begging for crankshaft / bearing problems . If I was planning to keep the 05 I wouldn't go this route but since I'm selling it or giving it away I don't want to invest a lot of money in it but I would prefer it didn't fly apart anytime soon .
I'm aware of the different size bearings used in these engines & won't know what I have until I have it apart but plan to install the same size new bearings . What do you think about all this ?

Response From Discretesignals

You start mixing parts together and your going to run into problems. The 2002 heads are different than the 2005. The 2002 uses the Jtech controller and the 2005 uses the NGS controller. They also have different emissions characteristics. Your better off having the heads on the 2005 checked out by a machine shop and finding a good low mileage salvage yard engine for the 02. They will probably want your old engine for a core.

Keep everything the way it was intended and you won't have issues.

Response From Logan Savage

I am aware I would have to install the cam gear with tone ring off the 05 head onto the 02 head & use the 05 intake manifold . It is my understanding the long blocks are the same . Are there other differences in the long block that you're aware of that I'm not ? I'm very capable of doing the part swapping & am more concerned with a possible bearing failure on the high mileage crankshaft . It has no bearing noise now though & I'm sure those 200,000 mile bearings have some wear . I know that no engine builder would recommend this but I'm very tempted to give it a try .
I really appreciate all feedback & I fully realize it's a crap shoot but I'm still wondering what you think about the crank bearings . A complete engine gasket set & rod & main bearings aren't really very expensive . I have checked & the same gasket set is listed as being compatible with both year models . Don't think I don't value your opinions because I do . By the way I'm retired & have plenty of time which I'm not putting much value on . If you firmly believe I'm setting myself up for failure speak up & say so . If you think I have some chance of success I'd like to hear that too .

So, why are you even asking if you already know the answer.

You sound like the daredevil that is waiting for his drunk buddies to talk him into jumping off the cliff.

Response From Tom Greenleaf

Logan: Was just watching this thread. Your first thoughts were you'd get laughed at or discouraged at least which you expected. Not laughing at YOU or personal but unless you just have time and the money to blow trying this it was all over for me when you stated the miles on these vehicles. There's a limit to vehicles in general if used up at all and clearly if they BOTH couldn't make the 200K (that alone takes real care from new) without needing the kind of work mentioned suggest not much else was cared for either.


All that even if engines were a perfect drop in match my 2 cents is don't do this.


Some is my opinion and some experience thru others failures as I wouldn't do this is that by the time a lower end of an engine is messed up at best you only buy some extra time as all the best machine work known doesn't make it new again,

Response From Discretesignals

Really don't think it is going to work. The combustion chambers are probably different and when you start swapping high mileage parts around, such as camshafts, that are worn the other parts they are matched to, your going to create more issues. Not positive, but I don't think 2005 uses EGR and the 2002 does? If the numbers on the heads don't match, I really wouldn't recommend swapping them.

If your mind is already made up to go ahead with your project, good luck and let us know how things turn out. Maybe we can all learn something.

Response From Tom Greenleaf

Logan - DS just added a couple more reasons and since I'm spouting off just share a tid-bit on even making NEW engines.
New - 100% new! The parts don't fit the next one perfectly and the machine bits are changed up to every 5 uses! At those extremes they still blow up by some % before ever being put in a vehicle!


That just machine work of mostly the crankshaft not even concerning any mid model year changes might go on to minimize how many blow up instantly, by that I mean bust into a broken mess of metal!


OK: What is high miles: It is going to greatly depend on quality of design AND care along the way. In general I say about 100K dependability drops off like a rock could be average. The exceptions are everywhere and you hear less about the ones that didn't make it that far,

I already think I'm going to like this forum . I have located a 2005 that was totaled due to a side impact behind the drivers door . It has 87,000 miles & still starts , sounds good & can be moved forward & backward a limited amount . The owner has offered it to me complete for $1,400.00 delivered to me . If there is no visible damage to the transmission & transfer case what do you think about buying it & swapping out the engine , transmission & transfer case for the 200,000 mile parts in mine ? Possibly even the differentials if they're not damaged . If I do this what other parts would you replace while the engine is out ?
Transmission front seal , engine oil seals & freeze plugs , anything else ? I really didn't want to invest that much money & work into the 05 because I don't plan to keep it but miscellaneous other parts off the wrecked 05 could be used on the 02 if needed . Would have to check but I think wiper motors , window motors & various other parts will interchange . I live in town but own rural property & could hide the wrecked body so it wouldn't be an eyesore for anyone .
In case you're wondering why I'm keeping the 02 instead of the 05 it's because the 02 is orange & the 05 is silver & my wife thinks the 02 is prettier & it will be her winter ride . lol

Response From Tom Greenleaf

Oh my! Has it ever dawned on you to look for a whole vehicle in good shape, checked out as much as possible and just deal with some surprises? Guess not and you are hell bent on fixing wrecks.


Miles, time, how stored with this new wreck. How long did it sit and more? Windows all broken and interior all wrecked too? Long list of stuff that goes wrong or hidden problems from wreck which is why they are totally not just body damage but strange crap happens down the road that might not seem involved but can be a choice when or if you needed a used part or whole component.


Color! Yikes! If that's a factor I give up on a used vehicle where any thought of its usefulness counts! "Gee, I like that color whether it runs or not because is looks good" -- can't win that game.


Buddy - miles and time plus how driven and where parked/stored all matters. With miles think a bit. Every part of that vehicle has gone that far. Some things doesn't matter but a lot does. Springs for seat go bad, upholstery wears out or sun damage. Rust if applicable always a concern. Motors for windows and locks etc., don't like not being used! I did do up antique cars and now driving one as my primary driver so do have a clue. Rear door locks went first! Just fixed them both no problem as I do that.


Glove box latches and sun visors - OMG some crap just never ends. Most new cars that don't get sold within TWO years are destroyed to be recycles for the materials if you didn't know! Gear cases can't sit way too long without oils splashing around nor seals on anything all go bad. Got the T-Shirt on this crap. Gettin' old and tired too for this stuff.


Not here to stifle your vigor and motivation just to warn you of details that can run you project into the RED meaning cost more than not doing it at all. If this is a dream and fun for you and costs won't harm you go for it. You may learn, win or learn that it was a bad move from the get go but it's all learning.


If you are just ambition driven to do this who am I to choose what you do? I did this crap relentlessly when VERY young and didn't lose $$ doing it but times were different too and parts up to whole cars could be had for FREE just needing a ton of dinky stuff but no longer road worthy which helped totally of course. For quite a while you had to pay to dispose of some metal thing car or whatever as new was much more practical for plain metals..........

Folks , if you don't have the patience or inclination to discuss this with an open mind maybe I'm not in the right forum . As I mentioned before I'm retired , have time on my hands , actually enjoy working on vehicles ---Mistakenly thought that's what this forum is about--- & do things like this for a hobby more than anything else . Recently bought a nice looking car with a bad transmission , bought a good used trans for $250.00 , paid $500.00 for the car , added a couple days labor & sold the car for $4,000.00 . I could go on about past experiences but I won't . In a previous life or you could say years ago I actually worked as a mechanic for 2 different new car dealerships .

My wife & I already have 3 nice vehicles in a 2 person household so I'm not out looking for a nice , road ready vehicle for our personal use but the wife did take a liking to the 02 Liberty . I don't normally give away vehicles but there is a young family member , still in school with a lot of extra activities that I'm considering giving the 05 to . Doesn't anyone enjoy working on vehicles anymore or is everyone now sign & drive & take the vehicle to a shop to get air put in the tires ?
I can't vouch for the above link but it lists the head as being compatible with both the 05 & 02 . If you're just going to tell people to go find a nice newer vehicle & sign & drive , what's the purpose of this forum ?

Response From Tom Greenleaf

Sport - If you can "flip" (buy low, sell high) cars with the demonstrated and admitted "shade tree" experience YOU claimed than go for it. Nobody here is paid a penny for sharing experience and some with very specific info.


This isn't quite as simple as you may think and admitted. YOU said and expected just what you expected in your top first post.
If unhappy with experienced free suggestions is all they can be without being right there than choose one of any of millions of places on the web to do what you are going to do anyway no matter what anyone suggests.


Why are you here then?


This thread is pointless,

Fine with me , go find someone to pump your gas for you . Say whatever you want , I won't be back to see it anyway & if it's within your power cancel my membership on this website . Ban me or whatever you like , I couldn't care less at this point .

Feel better now? Can't answer yet as I'll just lock this thread and yes even you can ask to re-open it by any moderator including me.


As others, wish you luck with the endeavor,

How much experience do you have with engine rebuilding?
