overhead lighting problem

[DRW1000]

Okay I have done my investigation into the door ajar switches for the sliding doors and the rear hatch. I don't how much of this Doozer mentioned but I am going to sum it all up in any event.

Sliding Doors- I was correct in that the 4 spring loaded contacts have nothing to do with the door ajar light so stop sanding them!!!. They only send the signal to the speakers and door lock actuators.
The other two items above and below these contacts do not have anything to do with it either (I am batting 500 now). I think they are anti-rattle devices.

THE DOOR AJAR SWITCH IS A PUSHBUTTON SWITCH ON THE BACK OF THE DOOR OPENING.
This is a pushbutton exactly like one on a front door and I cannot believe I never noticed it before. It is a simply momentary pushbutton switch. I have a photo of it but I don't know how to post it. If someone can tell me how I will post it and some others I took today.

Rear Hatch- This is the more complicated one. The switch is on the door latch meachism inside the door. when the door is closed this latch closes around the part that is onthe main part of the vehicle. This is the ajar position. If it is pushed closed further the latch moves farther and closes a contact. There is a switch on both sides of the door. I have photos of this disassembled.

Thanks for the info! You are right, if the doors are not ajar ... and the ajar lights are on, those switches are the concern. I now know where the lift switches are. Thanks again!

Do you have non-powered sliding doors? I always thought that three (of the seven) plungers on powered doors reported back to the door operator module the position of the door. And therefore, may be indirectly involved in the overhead lamp. Of course, there still would be no problem unless the door fails to close fully.

Good point 12Ounce.

I do have non-powered doors and thus only 4 pushbutton contacts. My findings obviously only difinitively point to my type of door.

Are yours powered? If so try and locate the button I am refering to. Perhaps it is there too because regardless of whether it is by human power or motor I should theink the door is either closed or it isn't and why have 2 designs?

The door ajar buttons are just as you described them ... on my '99.

In the case of powered sliding doors, I believe that 3 of the plungers can cause the door to actually "be ajar". Of course, the resistance of all seven of the plungers must be overcome by the drive assembly in the last bit of door travel ... therefore lubrication of the plungers may actually help the powered doors to close. My untested theory.

I am thinking that the extra three plunger contacts are the limit switches. This tells the motor when it should stop. I don't know what it uses for an open limit switch
