Bought car recently. Wangler runs great and looks good. Well cared for. I can't honsily say if it showed engin light when I purchased it. I know not to swift. I know most people are worried if engin light is on. Mind never shows. Took out instrument cluster to check if light blacked out or burned out. Light is a diod. Going to take cluster back out and check if connector pins or wires been mess with. I can tell cluster has been out before. Bottom cowling tab broken. Not very likely diod burned out. All other check lights show as they should. Carfax showed car passed emmission testing in the Dallas Texas area at 65,0000 miles. Watching gas consumption for miles per gallen. Trying to get schematics now. Still love car. Just don't want something later to bite me because I did not track this down. Thoughts and help appreciated.
