Well, found a harness and plug-in at the rear differential unplugged it and cleaned it with electronic cleaner spray but still doesn't work. Can I buy a scanner that will scan for the problems? Or do I have to take it to a dodge dealer so they can do it? Thks for helping guys I'll keep plugging along. Oh also noticed that the auto door locks when moving do not work so I guess that is also hooked up to all of this. Gary Mac
