I have a 2008 silverado 1500 4 dr. The doors were
crunched in and need to be replaced. Got new
doors at a used parts place off a suburban. Got the
doors in and everything was fine but when I
plugged in the master switch from the old door the
only thing that works is adjusting the mirrors.
Doors wont lock, no power windows, no heated
Check fuses and breakers, use a test lite to check for battery at the switch connector.
