Interior Lights never shut off ever !!!! SOLVED!!

[SHOclass]

I searched and found no resolution to my SHO's problem. The problem is that my interior lights stayed on after I opened the door to get in and never turned back off. key in, key out, lights "on" position or "off", dimmer switch all the way up ("click"), or down, it doesn't matter the interior lights just dont turn off. I've tried all my door springs, and even another dimmer switch.
Please advise.
Thanks. ('95 MTX)

EDIT - Solved !

The Culprit: Drivers side rear door jam switch.

The Issue : The door jam switch looked fine, and even acted like "normal" but after removing it (and others first) the plugs were bent inside the broken female end. *Two minutes to replace.

Thanks.

How did you check the Door Switch?? Could be a bad ground on the other side of the door switch happened with my 82 Blazer. Lights turned on and never went off. BUt it did turn out to be a door switch

Just pushed them in, and they sprung back out as they should.

The autolamp slider, if all the way up, can cause this IIRC.

I removed fuse number 8, which is far easier. and I have tried all positions with two different dimmer switches.

-not a valid diag. they will spring regardless, you have to pull them out to correctly check them....

-And what is the proper diag. after I remove them ?....

-the switches are powered at all times thru the fuse to the i/p dimming rheostat. the lights also flow thru the illuminated entry module, located behind the back seat tray. . make sure you are allowing the 25-30 sec needed for the module to turn them off after activation. there are full diagnostic procedures in the service manual and/or the evtm that are lenthy to type, depending upon your symptoms. just follow them and hopefully you will track down the problem.
