Robert, There is a good wiring diagram is on page 236 & 237 of the technical manual. If you don't have it, the colors are Green is the #3 fuse hot wire and 4 other wires go to the motor. Red/Lt.green, Blue/Lt.green, Green, Brown/Lt. green. The motor may be just froze up from neglect and no lubricant. There is also a limit switch on the inside that the contacts could be dirty.
