    I have a 2007 freightliner columbia and I replaced the cheap replacements with some with mirror heat. The mirrors I have use a black and white wires, but the original mirrors for this truck also had movement. Which color wires are for the heat ?

    Best I can guess would be to stick them with a test light and toggle your mirror heat switch on and off and see what lights up.

    You mean we need to submit Vin #'s to dealers and download full schematics to fix this problem?
