'02 Envoy, rear A/C fan doesn't work. Rear ballast Resistor?
Good morning all,
I have a 2002, Envoy XL, the front A/C works perfectly, but the rear A/C fan motor doesn't run. I had the same problem early on in the vehicle's life, and was told by GM service that the "rear resistor" had to be replaced, which they did under warranty. It then worked perfectly again.
So, now it's doing it again and I don't want to pay dealership prices to replace the resistor, if that's what it is. I have recently replaced the front A/C blower motor and resistor, as the motor was making a lot of noise. That problem is fixed.
BTW, the rear fan stopped working quite a while before the front motor started making noise.
My questions are: Where is the rear resistor located, and what steps do I need to take to replace it?
Thanks for any help you can lend.
