Replacing a faulty Door Lock Switch in a 2007-10 Silverado
First thing is to isolate the problem to make sure it's definitely the switch and not a fuse, wiring, or a actuator.
Driver's side doesn't work but the passenger side does.
Driver's side does work under any condition. etc: with door open or closed and with key on or off.
It must be the switch.
Tools required is a Wide blade slotted screwdriver and 2 small slotted screwdrivers
A 10mm 1/4 drive socket
After receiving the switch from the dealership. I compared it with the one in my truck.
First step. Pry the door handle cover off with a wide blade slotted screwdriver.
With some upward force, begin to gently twist the screwdriver to pry the cover off.
Here is what they look like. Take extra care. the mounting tab can easily break.
