We had problems with our front cowl flap motor. Intermittent operation. It wouldn't start if it stopped in certain positions. The problem was worn brushes and some broken wires in the windings. As new brushes are not available, a friend managed to adapt some simular ones from another motor by careful filing. With the aid of a microscope, he was able to re solder the "ultra thin winidings" that had also broken. This was over 2 years ago and the motor is still working fine.
These are the usual problems with these motors and if you know somebody with some basic skills, they are repairable.
