1996 Sable sedan; The other night I started my car and the door open light was lit and the interior lights were still on, so I went and checked all the doors and trunk and everything was closed, so drove to my destination, and when i shut the car off th lights stayed on. What could be causing this? then i disconected the battery so it wouldn't drain it and when i reconnecte it the lights came back on but this time when i started the car the door ajar light wasn't lit.

It sounds like your door jamb switch. When the light stays on go to each door and push the switch in to see if it sticks or if the light go's off.

I had the same problem for six months. Someone told me to spray each door with silicone and it worked for the door ajar light but the dome light was still on. I took my car to a dealer and they discovered I had turned the dome light switch on thinking i turned it off and had the door open while doing so. DUH!!

Good evening Slim 2193,



The switch in the left front door latch is comm for this issue. It is part of the latch assembly at the back of the door. I attached a picture for you of the location and the procedure for removing the door panel for access.
