heater speed control problem

Question From reh654 on heater speed control problem

Fan doesn't operate on speed 1-2-3 but works on 4&5
Vehicle is a 2003 pontiac grand am. Already tried a new switch

Response From GC Top Rated Answer

Sounds like a blower motor resistor, but will need to be verified by testing. Do you have a multimeter and know how to use it?

Response From reh654

It was the resistor thx for help.

Response From Tom Greenleaf

Glad to hear it's fixed. Closed now as solved and keeps spammers out,

Fan Speed

Showing 2 out of 8 Posts | Show 6 Hidden Posts
Question From bcobe on Fan Speed

I have a'98 Pontiac Grand Am and a year ago one speed of the heater blower(fan) started acting up. It would cut out when I stepped on the gas then start again when I get up to speed. Eventually it quit working while the other speeds were ok. So I started using the next speed up and now it is doing the same thing on the new speed, while the other two speeds that are left are ok. Is this the fan motor or a voltage regulator? what's the fix?

Response From DanD Top Rated Answer

90% of the time when we hear this kind of problem with GM heater blower motor, it turns out to be the blower motor resistor assembly.
You’ll find this assembly close to the blower motor housing under the hood. If you’re not sure what or where the motor is; turn the ignition switch to the run position and then the heater fan; follow the noise.
The wires that plug into the blower motor go to the resistor assembly. Usually only about a 10 or 15 minute job to replace.

Dan.

Response From bcobe

That's great to hear. I looked under the hood and found the resistor assembly. I ordered one and will put it in Monday morning. Thanks!!!!

Response From bcobe


Got the resistor replaced and there is no change in blower speed. Still cuts out when I step on the gas untill I get up to speed. Two other speeds work fine. Any other ideas?

Response From DanD

Sorry; like I said most times the resistor is the issue and I guess I should have paid more attention to your post about it shutting off while accelerating; which doesn’t make much sense at all.
The only thing I can think of right off hand is that possibly, the torque on the engine during acceleration, is pulling on a wiring harness, causing either a power feed or the ground for the blower motor to disconnect?
Maybe try turning on the blower motor (engine off) and start pulling and wigging any wiring harness that you can get your hands on?

Dan.

Response From bcobe

I will try that, but want to add that when I run the blower and rev up the engine in park, it doesn't do it. Can it be that the blower motor windings are getting weak for those speeds?

Response From DanD

Follow Tom’s advice and let us know what you find.

What I meant by engine torque is when you’re pulling away from a stop and accelerating, the engine will actually try and twist on its mounts. It’s not unusual to have an engine move an inch or two on hard acceleration and a lot more then that if you have a weak or broken mount.
You could try applying some torque to the engine by putting it in drive and or reverse; with one foot on the brake and then giving some throttle with the other.
Don’t hold the throttle on to long because while doing this the transmission temperature will go up by quite a lot and you don’t want to overheat it.

Dan.

Response From Tom Greenleaf


As Dan said, when speeds requested change the problem or especially when HIGH fan only works the resistor is the likely problem.

Same behavior with a new one rules that out. This pic shows the engine side with two wires going to the motor - this shows PS pump already moved but you get the idea. Those two wires must have good contact. One grounds the flare of the housing to body ground which could be intermittent. You could just use a jumper wire and add a temp ground to any good contact on the bolts of the flared part to engine ground while key on, engine off but when blower would and should be running and if added ground kicks it to check integrity of the regular one.

Makes sure those wiring connections are good - sometimes just removing and replacing gets a better contact.

Still nothing? Try tapping on the body of the motor with a light tap with hammer and an extention bar if needed - if that makes it behave for the while I'll blame the motor as tight at its bearings or moderate contact with it's brushes inside - not serviceable.

This problem is a little different so I'm trying to focus on what might snap it to with the engine off but key on "run" for the testing to rule out engine vibrations and alternator outputs as a cause.

Hit or miss with this and what works of any of those tries targets the problem a bit better. If a spade connector seems like the problem, try slightly distorting the spade with needled nose plier a tad to get a better connection, clean contact and I like a drop of WD40 or something on them to protect against corrosion.

Note: Depending on engine - either alt or PS pump is in the way of that motor to remove it,

2003 Grand Am GT - Hissing noise

Showing 6 out of 9 Posts | Show 3 Hidden Posts
Question From jordanpatrick on 2003 Grand Am GT - Hissing noise

2003
Pontiac
Grand AM GT
3.4L
86,000 M

Hello,

I was changing vent settings from blowing forward (heater, not AC), to defrost last week and as soon as I adjusted the vent selection dial I began to hear a "hissing" sound.

The noise is constant now, regardless of if heat is on, AC is on, or just turned off. It also continues despite which setting the vents are on, although as I change vent settings the sound changes a bit, almost like static.

I am not sure what to make of this, and perhaps the hissing is not related to the vents at all, and the timing was purely coincidental.

If anyone has any ideas, I would appreciate it.

-jordanpatrick


Also, to clarify, everything seems to be working correctly. I did replace the blower motor resistor today, but the noise started last week, and was unchanged after the install.

Response From Old 396

It's a vacuum leak. You have to remove some access panels and look up into the bottom of the dashboard with a bright light and try to track down the hissing sound.

Response From jordanpatrick

In this case, what should I be looking for, and how will I determine where the leak is located?

Response From Old 396

Jordan,

Hammertime and I were posting last night at the same time so I missed his answer. I'm seeing it now for the first time and I agree with it. The items he mentioned are the items you have to check. I don't know how to answer your novice question. What do you mean by novice? Do you have some skill? or are you totally new to auto repair. Again you are looking for a vacuum leak. You're going to find it by LISTENING AND FEELING for it. The hardest part of this job is getting up, into, and behind the dashboard. It depends on where the leak is. For example you may have to pull the radio and heater controls to locate the hiss. Like I said originally, remove the access panels under drivers side and passenger side dashboard, and get in there with a bright light. Maybe you'll see (and or) hear something.

Response From Discretesignals Top Rated Answer

If it is hissing in the off position, either the leak is at the back of the control panel or the source vacuum line. I'd pull the panel out and check there first. If you take it to a shop, take it to one that has an EVAP smoke machine. The smoke will show you where it is leaking.

Thank you for the advice. I am going to try and find the leak, but if I fail, I will keep that in mind.

Ok. I do have some skill, although I am very new to auto repair.

I will have some time tomorrow, so providing the weather is decent, I will remove the panels under and around the dash to try and listen / feel for the leak location. I have installed an aftermarket stereo, so I am least familiar with removing the radio, and dash controls.

Assuming I can locate the leak, what is the best way to fix it? I suppose it depends on the size / severity of the leak, but is there a standard method for dealing with a vacuum leak? Epoxy? Replace the section of tubing?

Response From Hammer Time

The mode controls are done through vacuum actuators and you likely have a leak in one of the lines, switches or actuators.

Response From jordanpatrick

Thank you for the reply.

Is this something I should have checked by a mechanic, or is it a relatively easy to troubleshoot / fix for a novice?

HVAC Blower Motor Only Runs On Highest Setting

Showing 4 out of 6 Posts | Show 2 Hidden Posts
Question From cycleman54 on HVAC Blower Motor Only Runs On Highest Setting

I am working on a 2001 Pontiac Grand Prix, 3.1 V6, with over 100,00 miles. The HVAC is manually controlled, 5-speed blower, with driver and passenger temp. control. The blower motor only comes on at the #5(highest)
setting. The blower motor also makes a whining, whirring noise when running. I checked the wires at the connector on the back of the switch with a multimeter. With key on, HVAC switch off, there is 11.7v at the orange(hot) lead, -.27v at the other wires except the brown wire(which I believe is the speed 5 wire) which shows 0v. With the key on, the position 1,2,3,4 wires show 11.7v and orange shows -.13, and the fan doesn't run. On position 5, the orange and brown wires show 10.95v and the fan runs. Does this sound like a faulty switch? The blower motor relay is incorporated in the blower motor resistor assembly on the HVAC control module.

Response From Hammer Time

You likely have a burned out blower speed resister causing the loss of blower speeds but this was probably caused by excessive current draw from a blower motor that is failing. I would replace both.

Response From liltruckjr Top Rated Answer

Agreed, replaced module on 05 grand prix and only lasted about 2 months then replaced again and blower moter... no problem for a yr soo far..

Response From Tom Greenleaf

liltruckerjr - this thread is from Dec 4, 2011 on a 2001 not a 2005 model year and original person probably is all set and done with what Hammer Time suggested. Please read dates as this one is done,

Response From cycleman54

Thank-you for the quick reply. I suspected that I was dealing with something other than a switch problem and I sought the input of someone who had more experience in electrical trouble shooting. Your help is
appreciated. Cycleman54

Response From Hammer Time

The switch is always a possibility but the resister is far more common.
