Last fall my power locks worked fine. Like when I'd use the key to unlock the driver door, the passenger door would unlock too. Or when I would be in my car and lock/unlock my door, the passenger door would unlock/lock. Then winter came, it got cold as hell and I thought maybe it got too cold for the power locks to work. So it was no big deal, I just got used to reaching to the passenger door lock to let a friend in. Now its hot as hell and the power locks still dont work. Is there a fuse that maybe couldve blown? Anyone else had this problem?

 

Perhaps if you tried to work a lock that was frozen, you snapped off the actuator control arm of the door lock motor???

Sounds like you'll have to pop open the door and see

 

Mine works intermittently. It might just be a loose ground or something.
