Another update. I pulled the motor/gear assembly and bench tested. It works just as designed. So my search continues. I tested the two limit switches. They show open normally and a small continuity resistance when clicked (closed) I always thought they opened when clicked .. but just the opposite. This now leaves the relay, the dash switch and the ignition switch as suspects.
Question: should the headlights come on when the headlight switch is fully turned on even with the ignition switch completely OFF? Mine do. I can see why the parking lights would come on but the headlights? If the answer is no then that might be a hint as to my problems. I'm looking more and more at the relay. The beat goes on.
