My door ajar sensor starting acting up last night. When I went out to the car this morning, it didn't matter which of the four doors I used, I had to SLAM the doors shut for the running lights and interior lights to go out. When I get in the car, I have to SLAM the drivers door shut so the door ajar indicator on the dash board goes out and the interior lights to turn off.

Does anyone have a clue on how to remedy this?
