Same location, under the dash, passengers side, waaaaaaay up near the fire wall, just above the carpet. It screws into the same area as the HVAC fan is.
The resistor does not exist on a dual climate control, instead its a module. I just replaced mine because it was shorted out, and the HVAC fan inside the car was running by its self with the car off. A common problem I guess according to GM.
GM Part number 89019166 and get ready for a huge hit to the wallet, mine ran $177.52.
The GM resistors, part number for my 97 if I had one, would of been 89019101 and they only run $50.26.
Ya...bend over for that one.
My new one from GM, on the left:
~F~
wait, are you saying your resistor was 177$? and they do exist, cuz mine is dual climate, and i had to change it last year, and what is that picture, thats not what my resistor looked like?
