I have a 2004 coach with a Power Gear touch pad leveling system. It is not auto-leveling so you must lower front and rear jacks and then use the corresponding buttons to finish leveling. All jacks lower and retract as they should but with all four jacks down if you press the button intended to raise just the right side of the coach the rear jack is the only one that responds, the right front jack does nothing. When I use the left side raise button both front and rear jacks respond together and it works perfectly. Possibly the touch pad is going bad? Anyone who has had similar problems with this system and can give an idea where to start for the fix it would be appreciated.
