2012 GMC Acadia. The auto door locks are not working:( When I try to lock it from the door or when I put the car in gear, the doors do not lock. Also, the back windshield wiper isn’t working, and the cruise control isn’t working. It seemed to all happen at the same time but possibly coincidental? I’m not a car-savvy person, but I don’t want to take it to the dealership because it’s so expensive.

Could be as simple as a blown fuse.

Blown fuse, common ground, or other. An independent auto repair shop can do it for much less than dealership. Shop around for referances.
