    Truck is a 2002 Silverado. The Lights in the AC/Heat controls has been dying. Mainly the bottom row of 4 buttons. Now the blower does not work when you select 1, 2 and 3. Still works on 4&5. Anyone have any ideas?

    If its loud, fast and runs on flammable liquid......count me in.
    Built LQ9...blah blah blah

    When the fan operates on the higher speeds but not the lower ones the blower motor resistor is shot. Not sure if that failing would have anything to do with the lights though.

    Figured it didnt have anything to do with the lights failing, just threw that in there.
