Can anyone tell me how to repair the interior courtesy lights when they remain on after locking the car or simply do not come on some times. Eventually the interior courtesy lights will go out. Is there a relay or something to be replaced? Thanks, Frank

 

sounds like a door switch to me...

The lights will stay on for a little bit after locking, but should be soon and dim out...if a door switch is faulty, it thinks a door is still open..
