What would cause the air conditioning in a 2001 Pontiac Grand AM GT to work on the 3 and above settings but not on 1 and 2?

Answer 1

The problem is definitely solved by replacing the blower motor resistor. The part is about $15 from Autozone and takes all of 30 minutes to install. You have to take out the glove compartment and then remove the resistor from behind the blower. The new resistor is a bit bigger than the OEM one, but everything fits together and works well now.

AnswerThe blinker problem is a recall your local Pontiac dealer will fix it for free. AnswerI just bought a 2001 Grand AM GT. I also noticed that the 1 & 2 setting are way low. I don't think that it is that they don't work, I just think they are very low to the point where it hardly even moves air through the cabin. Try putting the right knob that controls the direction of air to the top vents only. See if you can feel a trickle of air then. AnswerI have a 2002 Grand Am GT and had the same problem. It's definitely the "Blower motor resistor" which needs replacing. Cost me about 30 bucks for the part and 20 bucks for labor at the Pontiac dealership. Later. AnswerHave a 2001 GT and have had the blower replaced twice. Also noticed recently the blower is stronger at higher speeds ( go figure?)... I have 150,000 on the car and have had limited issues outside of new transmission and defective blinker issues... AnswerI also have the same problem in my 2001 Pontiac Grand Am and it makes it a real pain because its always really hot or really cold, no happy medium. Also I see that other ppl also have blinker problems with their Grand Ams - me too. Also I recently experienced the "bug" in the Remote keyless entry system that doesnt allow the car to start for no known reason. Resetting the computer using the key in the on position for 10 minutes solved the problem. The more I read the more Im considering heading to the dealership asap for a new vehicle AnswerI had a brand new key made and that resolved the intermittent pass-lock failure you were talking about. The key and ignition cylinder were worn and a brand new key (not cut from the worn key) solved the problem. I was told I would eventually need to replace the ignition cylinder, but this fix has bought me a lot of time.

This happened to me and my mother. We both have 2001 Grand Am's. It is the air conditioning unit/or air conditioning fan (I can't remember which). They had to replace it. Luckily it was under warranty. It happened again to my mother with the new part and she had to pay the second time because she was no longer under warranty.

The blibker problem is a recall on the 2001 Grand Ams. Your local Pontiac dealer will fix it for free.
