This may match our problem. After packing for the Midwest Rally Friday morning, we were ready to hitch, only to discover our electric jack would not work. The light on the unit worked, but not the motor. Please pass on any info you find out. It may also be our answer. According to the PO, the motor to this jack was replaced just last year, so age should not be a factor. (Thank goodness these electric jacks DO work manually or we'd have missed the rally!)
