BG, I had a similar situation on mine last winter. I figured out that if I unlocked the passenger door to avoid unlocking all the doors and then pushed the button down to lock that door then the pump got confussed and I could not unlock the trunk. If I locked that door with the key the problem disappeared. I also noticed a cable wire going along the back driver side to under the back seat. I havn't pull tested it yet as my problem no longer exists.

When the problem did exist all I had to do to REPAIR it was to lock and unlock the passenger door with the key and the car was back to normal.

Best of luck with your problem.
