    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.

    Default 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.
