There is usually a switch somewhere on the door frame that gets pushed in when the door is closed (which actually means that the swith contacts are open and no current can flow) but when you open the door the switch contacts are closed current flows and the dome light comes on. Check and make sure this switch is working correctly. There may be a circuit that keeps the dome light on after you leave your car and this may be the culprit also. It may also be that the dome light itself is starting to burn out. Aint electricity fun? LOL Seriously, most electrical problems have to do with a loose wire, bad switch or poor insulation. But then again it could be something more involved. It's like most problems, it's all about putting on your detective hat, having the right equipment and snooping around. Having a shop manual will almost always be a benefit. TommyTrouble
