I need the points I'm so sorry
I would say door lock actuator since it still locks manually just not electrically.
boy...sounds like you're stuck.
the only way (that I know of) to do that is to take off the inner door panel and access the physical mechanism inside the door. Warning, can really mess up your door.
I would just take it to a reliable mechanic, NOT YOUR DEALER they always overcharge.
hope this helps
I drive a 1998 Pontiac grand prix, and my door lock is broken but I don't know how to fix it. It's strange, if you hit the door lock switch you hear the sound but only the passenger door will lock not the driver. I always have to lock it manually. Does anyone know what could be the problem? Is a motor or something broke? If That's the case why does my passenger door lock still? I need you guys help please
