Blower motor on my 2000 Grand Prix only working on Hi.
Blower switch has five settings 1-5. When I purchased the car used about 7 months ago, the number 1 (low) did not work and 2-5 did work fine. Last week 2,3 and 4 went out and now only high (#5) works.
I'm assuming it may be the resistor pack, where can I locate the resistor pack and what does it look like.
Besides the resistor pack, what else can be the problem.
Thanks in advance,
Wes

It's likely not your resistor stack- that piece is made if some very heavy stainless wire, and would likely cause a meltdown of the suitcase before total failure. I've seen failed ones on GM products, but that's usually a 25+ year old part that has corroded (the connecting terminals) or had been poorly crimped in the first place (extremely rare). After I get off of here, I'm going to look it up, but my money would be on the fan switch or the control panel. What type of HVAC do you have- automatic or manual?

OK Wes- I looked it up, and I have to admit you were right. The manual says that the resistor is the first place to look, and the first piece to replace when your problem crops up. posted_image

The resistor is located behind the right side of the dashboard, on the right side of the "control module"- the blower suitcase. It's directly below the motor, say a bit to the right of the console. You will be looking for a connector that is an elongated oval, and has 4 wires- a purple, light blue, tan, and yellow- they all look to be 18gauge. You'll have to remove at least the underdash cover (easy) to get at it.
