I took my 2020 GMC Sierra at4 to body shop to fix a damaged driver and rear driver side door. They fixed the doors. I don’t know if they are new or if they did body work. Everything works except the silver lock /unlock buttons on the outside door handle. The lock unlock switch inside works. The fob works. The passenger side buttons outside work. Just the button that should work when the key is in your pocket.
i am guessing there is a loose wire that was not connected. Where do I look?
Thanks
