has anyone had problems with central locking actuators going haywire? my passenger rear will only cycle into the locked position, then wont do a cracker more. i pulled it apart and rotated the contacts, but all it will do is go from unlocked to locked, and then refuses to do anything else. i went to a wrecker and plugged in one of thiers and surprise, surprise, it did the same thing. i'm suspecting the body module, but am willing to fire a couple of tests on it if anyone has any suggestions
