Long time reader, first post.
I've got a bit of an electrical gremlin that took up residence in my power lock system. As backrgound, I have the factory keyless entry (AU0 RPO).
The Symptoms:
With the vehicle off and sitting for a while (i.e. overnight), I can open the door, and work the power locks by either the driver or passenger keyswitch, or by the keyfob. If I start the vehicle, after a few seconds, the the power locks (keyswitchs on front doors, or keyfob) stop working and the the swtich system will try to actuate intermittantly (as indicated by a relay clicking sound somewhere in the dash area) and an accompaning lighting of the overhead dome lights. In addition to the intermittant actuating (with relay click and overhead light), I can do the same thing by pressing the lock switch (causes relay to click and overhead light to come on). This symptom will continue untill I shut the ignition off, and let the vehicle sit for some time (15+min or over night, etc).
Here's where it get's interesting...
What I've done:
1. Pulled open the front driver and passenger door panels, disconnected the lock switches; tested as above. Result: No change, same behavior. Reconnected switches.
2. Pulled open the front driver and pannenger interior door panels, disconnected both lock actuators. Result: No change, same behavior. Reconnected both actuators.
3. Pulled lock relay under dash. Result: No change, same behavior. Reconnected relay.
At this point, I'm at a loss on what to check next; I'm thinking eithe the lock control module or the remote control door lock reciever are acting funny. Also, haven't check rear cargo switch.
I have the 4-volume factory service manuals and electrical diagrams, and am pretty handy with things.
Any advice would be greatly appreciated!
Thanks.
