1. General cost to examine why drivers side mirror not working - and cost

My wife bought a 1988 Cadillac - in 2002 - which had only 22,000 miles on it. In 2005, when her driver side window failed to go up when the switch was pressed, I took off the door panel. The bolts that held the motor had pulled loose, so I replaced them with bolts using lockwashers. The glass only needed to be set back in the track. While I was in there, I found that the wiring to the side mirror was held in place with electrical tape. Evidently, someone had a problem previously. I soldered the wires and covered the joints with heat-shrink tubing for insulation. They still work fine. Get inside the door if the fuses are good.
