when I was driving I got a message that the door was open when it was not. after that everything on the drivers door controls stopped working.
none of my drivers control's are working there is no power to the door. on 2009 GMC Sierra 1500
Check the fuses, most likely under the hood there is a maxi fuse protecting that circuit, it may be blown. Another scenario, but not as likely on a four year old truck, is a open circuit (broken wire) in the rubber wire loom that runs inside the door.
