2002 Cavalier Dome light turns on 4-5 minutes after doors are closed?

My 2002 cavalier, four door, base model has a dome light issue. Doors are all closed, dash dimmer switch is in off position. Dome light dims and shuts off in 15 seconds as it should. Light stays out between 4-6 minutes and turns back on by itself and will not shut of until you open and reshut door. Does Not do it while car is running. Only when car is parked. Bad Door Switch? Bad Dash Dimmer Switch? Bad BCM?

Disconnected the battery and let it sit for fifteen minutes. Reconnected battery. Seems to have solve the problem for now.

With this changing the pattern, I'd say it was (is) a BCM problem.

Problem not solved. Going to try replacing one door switch at a time. Then try Bcm. Can the Bcm be reprogrAmmed? Or do I just buy a new one and install it?

A new BCM will need to be set up with a Tech2 scanner and the theft system will need to be relearned. There is no actual "programing" that takes place with the BCM, you use the scanner to let the BCM know what options the car has.

Thank you. Will let you know what works once I get it figured out.

Prpblem SOLVED. It was either a wet connection at the drivers side front door switch or a bad switch. Either way, new switch with cleaned and greased connector intalled. NO MORE LIGHT PROBLEM. It is worth mentioning too...that the new switch is self adjusting. Install switch, close door with force, switch depth self adjusted. Thanks for your help. Hope this helps someone else.:smile:
