I've searched and searched multiple GP sites to no avail on my problem. If this is a newb question that has been answered a million times point kindly point me in the right direction to where the solution(s) have been posted.
Vehicle: 2000 GTP Coupe
Problem: Power door locks do not work at all. When using the key fob or the door switch, the relays under the driver dash click and the lights and chimes will respond when necessary but nothing locks.
I've probed the switch connectors as well as the actuator in the doors. At the switch I get ground switching to the white and blue wire when pushing lock and unlock on both doors (cant remember which is which at the moment) and constant ground at both black wires. The gray wire has nothing. I assume this system switches ground to trip the relays. When the relays trip, should it send 12v to the actuator? Any ideas on what to look for / check? I'm a Ford guy who is new to GM's so I don't know everything that controls the lock system in these cars. Any help would be appreciated greatly.
