Doors on the passenger side won’t lock
I have a 2002 Ford Focus zts. Bought this car recently and the passenger side doors (front & back) didn’t lock. You could hear it trying to work but it never would. I’d just lock it manually myself. Last night however it stopped working all together. Can’t hear it try to lock AND I can’t lock it manually. It’s like stuck on the unlock position. Any idea what could be wrong and what I should do? I don’t know much about cars but I can follow directions easily. Any help would be greatly appreciated thank you!
