Sometimes the wires running to the power seat will rub through between the carpet and the floorboard and create a open should blow a fuse tho too

BCM=Body Control Module.......but are you sure the batteries are 14volts etc.
I would say yours needs a reflash!Did this happen all of a sudden or what,you aren't giving us much details....

Hard to say man,I know some people swear the reflashes help with intermittent trouble,but if a wire gets chafed or shorted then it'll never work properly[or at least when ya want it to]..

The most common chafing problem on a GMT900 and the SUV's is just to the left of the parking brake. The wiring harnesses are run tight there and the parking brake can and will rub through causing very very bizarre electrical malfunctions that happen all at once but otherwise have no common circuitry or fuses.

Everyone should take a few minutes to check their trucks out. If you see any signs of rub or potential, use some good zip ties to pull the wiring harness up and out of the way. Cycle the parking brake pedal by hand a few times while looking up and to the left of the mechanism and you should be able to see where the potential lies.

i checked all fuses which there isnt a fuse for the drivers door. i checked the wires between the door and frame nothing... took the door panel off and made sure all the wires were connected.. finallly i just called a gm dealer and the guy thinks its the whole switch gone bad.. so tmr morning i gotta take it 30 miles with the window down.. haha.. but the only question i have now is, since i voided all warranty on my truck by takin exhaust off and chiped will they like black card me?
