Reply to "headlights"

A few suggestions: First, take the limit switches out one at a time, take the covers off and spray them out with TV Contact cleaner. Wire-brush the external contacts. Second, the headlight motor/gearbox is identical to the window lift motor/gearbox, and is subject to the same splitting of the plastic drive gear. If the gear splits, Hercules couldn't rotate the gear. A bronze "window" gear replacement is then called for. Third, the drive motor has the world's funkiest connection to operate as an un-grounded DC motor; the key is a tiny insulating grommet attached to the motor case. If the grommet cracks, water & road debris can penetrate the insulator and create a partial short. The fix here is to discard the grommet entirely, connect the motor wire to its loom wire directly, insulate the connection with shrink-tubing and tie-wrap the thing away from any metal it might reach. One or more of these should fix your problem; incidently, they all assume the fuse contact is perfect. Be sure to thank Joe Lucas in your evening prayers....
