All of the door locks but one on our 1999 GMC Suburban will not lock or unlock when using either the remote or the door lock switch. Is there a relay that accuates the locks?
there is a relay but if it were bad none of your locks would work. your problem is the door lock motor it is a little electric motor that actuates the lock. its also called a door lock actuator. kind of expensive and a little difficult to replace.
