When the doors close, the interior lights won't shut off. They will go out sometimes for a short period of time, but always end up coming back on. When I move the lock mechanism inside the front drivers door while it is open, the lights go out and stay off. I sprayed the lock mechanism with wd40 but that didn't work either. I had to remove the fuses from the block in the trunk.

Does anyone have any suggestions before I take it to Cadillac and get reamed when they put in a new door lock mechanism? Thanks.
