2002 Saturn L100 Electrical

On ur tail light have u ever had ur tail light campaign done?U can tell if it had if it has a extra plug jumper harness and it is blub sockets bolted in place instead of the blubs just twisted into the tail light assembley. If it hasn't been done Saturn will fix that for u free of charge. As far as ur dome lamp coing on by itself u could have a bad body control module dome lamp or bad door jamb switch it's hard to say without checking it out. On ur headlights getting brighter when excelerating or flickering there was a buletine from Saturn saying that was normal. But to be on the safe side I would make sure the battery cables are clean and tight the postive posts on the factory batterys leak on those cars into the battery cables. Also have the battery and alternator tested as well. Let me know what u find.
