Well, I traced the problem. The battery was not holding a charge. Also, numerous poor connections. It appears that the fuses were rotating in their holders and ovalated the connectors. Replaced the entire unit with a junkyard part for $40.00 and bought a new battery. Everything now works - signal light, window...it was all due to the fuse box being worn. Froze my fingers. I hate it that my garage is full of bikes and other cars so I have to work outside in the rain & snow, in the worst weather we have had in over five years.
Oh well, its all fixed now...and everyone's advice was put to good use. I really appreciate it.
Time to throw some logs in the fireplace & pour a stiff shot of rum.
