    Blower motor resister, they are usually the culpret. Its hardend wires, it is usually bolted to the truck with a screw or 2, if the hardened wires are rusted or corroded then that could be the problem, they are around 20 bucks to replace.

    replaced the resister, still nothing

    Ok , So I pull the resister (what a pain) looked ok but I went and got a new one and still no action from blower. Do the speed control switchs ever fail ? Any thoughts? Thanks, Steve

    Ok, So I pulled the switch and that was it. If you look real close at the terminals the plastic is a little melted next them, $39 bucks to the dealer and it's good to go . Thanks, Steve

    I replaced my resistor a few months ago, and the replacement has failed already. The cuicuit board on the resistor had a burn mark on it like the last one. What should I look for now.

    the blower motor may be pulling to many amps
