Back door not locking.

[alxval428]

I was wondering if anyone has had a situation where their truck is doing the opposite when you go to lock the truck. For example when I lock my truck all doors but my back passenger door will lock. (If all doors are locked the back door will then be unlocked, but if all doors are unlocked the back passenger door will be locked.) I was wondering if anyone has had this problem before and if they found how to fix it?

Sounds like a wire is swapped on the actuator for that door. Did you do any work on that door recently?
