RE: Driver Door Problem
OK.
'93-'96s have a plunger type switch on the front jamb of the doors and often the plunger sticks in. Usually, spraying it with WD-40 will free it up.
'97&'98's use an ajar switch inside the door latch that also may stick. It usually sticks in the open position, keeping the "Door Ajar " warning and the interior lights on. On the rare occasion, it will stick in the closed position. Spraying a good amount of WD-40 into the latch where it catches the striker may solve your problem.
Sometimes, the connector to the switch comes unplugged, but let's not talk about going inside the door just yet.
One last thing: does opening the driver's door trigger the "Door Ajar" warning but not turn on the interior lights? I hope the answer is no, because that opens a network can of worms we'd rather not get into!
