    I replaced the heater/ac control in my 2002 2500hd silverado because some of the lights were no working and the first 2 levels of fan were not blowing, so after replacing the lights work and the fan still has same problem. i checked fuses and all look good but i cant seem to figure out why 1,2 on the fan switch will not blow air, 3,4,5 all work great. any ideas?

    Definitly blower resistor and or connector harness. Have seen both bad often. Harness is stupid expensive from gm but not to much u can do about if it needs it.:realmad:

    I also lost 1,2 and 3 speeds on my blower motor on my 2003 earlier this week. I picked up a new resistor from the local auto parts store, it was only $33. When I get a chance I'll try and find where it is located on the truck. I took a quick peek behind the glove box but didn't see it.

    Pull the hush panel down from under the dash on the pass side and look up, you'll see it. :)
