First post. Go easy. My LH rear door lock failed to operate. I stripped the door down and removed the lock. I connected the replacement lock to the plug and tested it and there was no response. I have contacted the seller who has said to send the lock back but I don't want to waste his time if the problem is with my car. Is there any way that I can test voltages across the pins on the plug to see if it could be a problem on the car side?
