Hi there,

If the motor is working, is this via the switch? If so the problem must be with the regulator or the motor drive gear, you will have to pull the trim and inspect what is going on with the regulator.

You will have to work back from the motor plug, checking power through the switch, make sure that the relay is ok, how many wires to the motor? If 2 the problem may be with the change over relay, check this out, I will look for a manual and try and get some more exact information.
