The driver's side door lock actuator on my '05 equinox is not working (the switch is fine, the other doors lock and unlock, and both manual mechanisms work). I opened up the door hoping to be able to just put my voltmeter on the wires leading to the actuator to make sure it's actually bad before ordering a replacement, but gave up when I realized I can't reach the actuator well enough to remove its plug and it seems it will be a big job to pull it out.

So my next best thing is to at least check the harness connector at the door jamb, but I can't find any pinouts to tell me which pins to check. Anyone have this?

Also, is there a trick to disconnecting it? I really wedged a screwdriver in there and actually pulled the jamb-side of the connector out of its hole, which led me to the secret little pin that holds the connector shut. I don't want to break it trying that again if there's an easier way.

 

the wires in the door to the a-pillar will be broken. Open the door, pull the rubber loom back and inspect.
