SO.. About two weeks ago we had a about 4 inches of snow fall and I i didn't drive my car for about 4 days. When I finally shoveled all the snow away, I sat in my car to warm it up. Then I noticed that the button to lock the doors didn't work. No big deal to me I just used the button on my key chain and it worked fine. A week or so passes, barely any snow on the ground and warm out I get in my car to go home and when I lock the doors with the button from my key chain the door unlocks. No big deal, I figured I pushed it too hard so I push it again. After driving for a couple of minutes it unlocks all by itself. This happened my whole ride home. I check the button on my key chain to see if that's stuck and it was fine. No lights indicate that any doors are open. The next day I open and close every door myself but I have the same problem. I try to lock each individual door manually and still the same. What could be wrong? Who can fix it?
