Front AC Fan Switch.

[Earl33]

Only works on 3, 4 and 5 Fan Won't blow air on 1 and 2. 2002 model Tahoe. Anyone else have issues like this. AC blows cold front and back. Is it something simple like a bad switch? Or something more?

Probably just the switch. You could take it out and test it with a multimeter.

I have that on my **** to do list but always find other things to do instead of pulling it out and checking it. Is this a common problem?

I haven't seen it yet in the 2000-2006 section but my friend has a 99 yukon and his fan blew hi no matter what speed the switch was on. Turned out to be a bad switch.

Most likely it's the blower motor resistor. Any auto parts store will have it.

Thanks for the help guys. I pulled the switch out last night and checked it with a meter and it was good. Stopped by the local AutoZone this a.m. and picked up a resister. Got home and as soon as I got the old one out I could tell it was screwed. Problem solved.

Thanks again for the input

Where is the resistor located?

Where is the resistor located?

Behind the black cover panel between the glovebox and floorboard. It takes a 10 mm socket (I think) to get the cover off.
