2004 HR Ambassador Rear Passenger Slide One Motor not Running

Got a 2004 HR Ambassador that has a passenger slide rear slide with two motors. Problem is the motor on left of slide isnít working but right side is. So if you hit the button the right side tries to come out but left is jammed.

The messed up motor is visible in the basement bay along with PowerGear e-sync module. I canít for the life of me find the right side motor, itís not under the bed.

Any tips on troubleshooting it?

Look in the wheel well for a screw on plate, Monaco did that on many of their motor homes. On my 2005 Monaco Diplomat the small rear bedroom slide always came out okay, but not perfectly. Years later, I was repairing and adjusting the main slide and found that Monaco typically only used one motor with a drive shaft. The drive shaft connected two drive gears together. The drive gears fit over the shaft and were pinned in place with a soft bolt and nut.

After figuring out how they made them work and adjusted the main slide, I attacked the small rear slide. It had just one motor with the driveshaft. The pin in the second gear had apparently fallen out years ago, but the room was small enough that the slide still worked. I replaced the pin and the slide worked better than new.

I can't imagine why they would use two motors on that slide, or any slide less than 16 ft in length. Unnecessary cost and installation problems. I'm confident you have one electric motor, possibly driving a shaft with two gears if the slide is longer than about 8 ft. If one side moves while the the does not, the gear on that side has probably broken the pin that connects it to the drive shaft. However, bedroom slides typically have a direct drive and no gear shaft. The slide isn't big enough to need to two gear drives.

Motor was in tire well, it tested fine. Itís the Esync 140-1140 thatís not showing voltage to the motor on left side of slide.

Anyone know of an alternative device for sync? I canít find that part anywhere online

Try M and M electronics. They may be able to repair it, or recommend someone who can.
