    All my dome lights and courtesy lights stay on now. I have all the bulbs removed from them. It just happened once last x mas and now its stuck on. It doesnt matter if I push the pin switches in or not. Its weird. runs my battery down constantly

    You probably have a bad door switch.

    Yep I'd bet the door switch is shorting out on the body.... same thing happened to me, and if you have to replace them( NAPA ) I'd suggest putting a washer on them first or when you screw them on they will not tighten down all the way due to the threads stopping short and the thicknes of the sheet metal....

    Isn't there also a position on headlight/insturment pannel dimmer switch that turns on the interrior lights? Maby that is the problem

    the lights are constant power with the door switches grounding them to light up.
    I just removed the door switches entirely.
    they like to rust

    I put a aftermarket dome light in and it started grounding out through the housing- therefore my dome light stayed on all the time. The only other thing besides the door switches could be a wire thats grounding out making the lights go on.
