I need help with this issue please. My 2008 Chevy Silverado unlocks the doors by itself. I can lock my doors at any time, come back say in several hours, and they are all unlocked. This issue is driving me nuts. Anyone have any ideas? I asked my GM Service Advisor and even he is stumped.

Well I think I may have just solved the problem. In the process of removing the passenger side door panel, the lock/unlock switch began to work properly. It previously would not unlock any doors. In inspecting the location where the door panel bolts were located, I discovered the wiring harness that goes to that door switch was being pinched between the door panel and the door at the lower door handle bolt location. After moving the harness and reattaching all the bolts, the switch is now working properly. I have locked all the door and will now wait till this evening to check if the truck is still locked. Keeping my fingers crossed.

(The wiring harness must have slipped down when I replaced the door speaker a year ago. This problem happened right after this. Others who have the same problem should check the wiring harness in the doors.)

 

On another note, my GM Service Advisor (Mark Cordes) at Covert Buick/GMC in Austin, Texas is an amazing Service Advisor. I recommended him and the dealership to anyone. There is not much I can confuse him with. Two thumbs up!!!!

 

Awesome news, medic115! It's great to hear that Mark at Covert Buick GMC has been so helpful throughout this process. We'd be happy to file a formal dealership compliment and relay the message back to Mark. If interested, please private message us your VIN and contact information. Thanks for your feedback!
