So I have a crazy issue with my passenger side door lock. When I hit the key fob or the electric lock inside the car the door lock just “ twitches”, meaning it just barely moves but not enough to move the lock. I took off the door panel and inspected it and with the door panel off the lock assembly moves easily manually. Also inspected the door panel and there is noting rubbing or obstructing the cables it lock assembly. I know the locking mechanism has issues as I just replaced the whole lock mechanism in the drivers side… and literally two months later the passenger side is giving me issues. Any ideas on what may be the problem? Trying to not have to pay for another whole locking mechanism. Thanks Fellas.
