Im having problems with my passenger door lock it seems to be stuck when its in either lock or unlock position, to lock the door i have to press on it and i can hear something mechanical not sure if its a motor of sorts. When i unlock the door from driver side all door unlock except passenger door but all of the other locks go back to lock position within a sec. If my passenger door is unlock position and i try to lock the car from driver side all doors lock except passenger lock but all locks go back unlock position within a second.
Does anybody have an idea of what could be the problem?
Thanks.

 

Sounds like a rod is sticking you need to remove the door panel and inspect the rods for binding and use some sort of a film lubricant on the clips that hold the rods. I can't recall I'd the pass door has a keyhole if so put in the key and turn it without forcing it and that will tell if the lock rod or the tumbler rod is binding up.
