Service 4wd light

Question From twowatt on Service 4wd light

I have a 99 Chevy Silverodo i tried to put it in 4wd when i did it stayed in 2wd i tried a couple of times with no luck then the light went out by the button and the service 4wd light came on. I shut the truck off then started it again and the button light came back on tried to put it in 4wd and the same thing happened. How do i fix this and is thair a way to put it in 4wd by hand PLEASE HELP ME.

Response From Guest Top Rated Answer

I'd say you have either a faulty 4wheel drive actuator in the transmission, a faulty button assembly, or check your wiring from the button assembly to your transmission 4WD actuator.

Response From twowatt

Hi i found out that the switch itself is bad is thair a way to bypass the switch like useing a fused toggle switch to send power.

Response From way2old

I would get a switch. Looks much better than a toggle switch.

Question From TheChevynator on 93 Suburban no 4wd

My suburban wont go into 4wd hi or lo when I shift the selector.This vehicle has no locking hubs.It has CV axles. I tested the 2-wire actuator plug with a test light and got no voltage on green/grey wire.The ground wire was OK.The 4wd fuse is OK.It worked fine a week ago.What could be the problem?

Response From oakleyrodney

Is the fourwheel drive electricaly operated or vaccum operated?

Response From TheChevynator Top Rated Answer

I found the problem.It was the 4wd actuator switch and plug.The plug and switch on top of the transfer case was badly corroded.The prongs in the connector were like mud.I connected 2 of the 3 wires going to the switch and walla I had 4wd.Thanks for your response any way.It looks like you were headin that direction.

1999 GMC Jimmy, 4x4 not engaging front axle

Showing 2 out of 11 Posts | Show 9 Hidden Posts
Question From dustin8420 on 1999 GMC Jimmy, 4x4 not engaging front axle

1999 GMC Jimmy, 4.3 liter engine. So we get no error codes, doesn't seem to have a vacuum leak or a problem with the transfer case, but the front axle doesn't actually engage. We're at a loss for how to diagnose problems any further and we are hoping for more ideas here.

When changing into 4 high the light changes on the dash as if the computer thinks all went well, but the front axle doesn't actually engage. The diaphragm under the battery box seems to to function properly, which means there shouldn't be a vacuum leak or a problem with the switch on the transfer case. So how do we diagnose this further?

Response From gsferraro

Is this a 4 button switch on the dash? So when you hit the 4 high button, does it blink and then stay steady on 4 high?

Response From kev2 Top Rated Answer

no flashing 4wd controls, no codes, actuator is moving next I would check cable they are known to snap break- try google - "jimmy 4wd actuator cable" might be a tutorial

Response From dustin8420

Okay so I had some trouble with the housing that connects the actuator cable to the differential. Bought a new housing, got everything connected and... no dice. Made no difference.

Response From Discretesignals

When someone activates the 4 wheel drive, do you see the actuator diaphragm suck in and pull the cable? Should be able to pull the cable around 3/4 inch.

Response From gsferraro

I would look at that front actuator, there should be 2 wires going to it. This part has a high failure rate and has been updated. You would have to take the part out(it should unscrew) and bench test it with a 12 volt source, one way the actuator will come out and switch the wires it will go back in. How i test them is, i hold it against my work bench and apply the 12 volts and see if the actuator comes out. (sorry for the late response, is was away)Gary

Response From kev2

I think this is a vacuum operated cable actuator - not the electrical as colleague mentions.


In first post OP said NO vacuum leaks (my bad I ASSUMED)- Maybe we should revisit the operation and vacuum apply and routing....

Response From gsferraro

This car has a transfer case control module, right side kick panel

Response From kev2


test trying to add picture

Response From dustin8420

Found a perfect video running through the process of checking and replacing the actuator cable. So thank you very much sir! We're replacing the cable regardless of whether it's bad or not, but I will drop a status update later today after I've had time to change it.

Response From dustin8420

It's a 3 button setup and yes blinks and then stays 4 high (or low).

Power Steering Fluid Help!

Showing 2 out of 2 Posts
Question From Capman278 on Power Steering Fluid Help!

Hi everyone, I drive a 1998 GMC Sierra 1550 Vortec 5.7L V8. Two weeks ago, my power steering pump stopped working so I took it to the mechanic and had it fixed. I got the truck back a week and a half ago. When I was driving it off the parking lot, I noticed that the steering wheel was "rubbing" and I noticed this "whining" noise similar to a super charger. Any ways, I drove the truck for about 2-4 hours more and noticed the noise and the rubbing in the steering wheel getting worse. I was going to take it in tomorow to have them look at it but for some reason I decided to check the power steering fluid level and it turned out to be completley dry. I know that the system has not been leaking because I got under my truck while it was in the mechanic's parking lot to look at my 4wd actuator before I drove away and there was no fluid. And,theres none on the floor of my garage. So the guy obviously neglected to replenish the fluid after draining it. My question is, how much if any damage could this have done to the new pump or any other components? Should I demand for a refund and take it somewhere else or maybe have him fill the fluid or completley replace the pump?

Thanks for any responses in advance!

Response From Hammer Time Top Rated Answer

Fill the fluid and see what happens. See if it quiets down and stays full. Don't be so sure he forgot to fill it.

1993 chevy s 10 4.3 v6

Showing 2 out of 5 Posts | Show 3 Hidden Posts
Question From kaysonecarraher on 1993 chevy s 10 4.3 v6

hey there my 1993 chevy s 10 4.3 liter v 6 is having a few problems.
it sat for five years so i was expecting issues. when i got it it wouldnt start obivously, so far iv replaced the spark plugs the oil filter and oil, the gas and a fuel pump also the egr valve as well as the distributor cap and rotor. it was also missing a 30 fuze( it was a faded identification fuze port but it was clear that a 30 was meant for it.

it starts up and runs strong however its idle is way too high.(please note it has a throttle body not a carb)
while in motion the car pulls itself up to 25-30 mph after about ten minutes it bogs down and dies and refuses to start back up.
it also has a check engine light reading a code fifteen (coolant temperature sensor voltage reading too high) i think it might be the o2 sensor causing the issue or possibly the fact that its just gonna run a lil rough for a lil while then regulate itself off. please help if you can or atleast give me some insight on possibilities

Response From nickwarner Top Rated Answer

Your vacuum hoses and all the intake gaskets are almost old enough to go into a bar. Change the hoses at least. Why would you suspect an oxygen sensor being bad when a code comes up for a coolant sensor? That is the code that needs the be looked into as it can and will make this run like a bag of crap.

First, get about 5 feet of the top 3 sizes of vacuum hose at your local parts house. Get a fresh razor blade to cut it and change one vac line at a time on this engine. If 4wd remember there is a hose going to a vacuum pod and down to the diff for the 4wd actuation too. Change them all, I don;t give a damn how good they look. Hose is cheap, and old ones are not to be trusted.

After you have done that, you need to look at the wiring plug for the CTS and do some testing on it. Do you have a multimeter?

Response From kaysonecarraher

ah makes sense ill give it a shot and im not too sure what a multi meter is (sorry people have different terms for different things) i have a voltage meter and a ob 1 code reader. and what is the CTS?
again sorry for my incompitance

Response From Tom Greenleaf

CTS I think is yellow and black wire to a sensor for engine coolant near thermostat. You can test it for Ohms at what known temp but as Nick said the plug right there is also a problem spot. That item AKA ECS tells the thing how warm the engine is so it can deliver the correct amount of fuel.

BTW - If this was outdoors for five years without intense storage preparation expect a zillion things to do or will happen/fail soon. Brakes are probably junk no matter how good they were among many things,

T

Response From nickwarner

No need to apologize for not knowing something. If you knew it, you wouldn't be here and thats what this place is all about.

CTS means coolant temperature sensor, which tells your computer what temp the engine is at. When the engine is cold, the computer richens the mix with extra fuel by commanding the injectors to stay open longer than they would if the engine were cold. Its the modern day version of a choke and works better than the old carb systems for cold starts. But if the coolant sensor is bad or its connection corroded up the computer is fooled into thinking the engine is still cold, and dumps a rich mix into it that will cause it to bog down and eat fuel badly. Your timing of when this occurs which is about how long it would take to reach operating temp in Tacoma points to it as a possibility. However it can also be caused by other things like a vacuum leak. Many times its not one big leak, just a bunch of smaller ones that have added up. With the age of this you would want to replace all those vacuum hoses as they are cheap and easy to do, and even if not the exact issue at the moment you will save a lot of trouble down the road.
