Q: What are the troubleshooting steps for electric rear view mirrors on Lincoln Town Car?
A: Most electric rear view mirrors have two motors for adjusting the glass - one for up and down and one for left and right. Some mirrors also have electrically heated glass defroster circuits. To troubleshoot, roll down the windows and operate the mirror control switch through all functions. Listen for motor sounds. If the glass doesn't move but the motors are running, there may be a problem with the drive mechanism. Check the Fuse if the mirrors don't operate and there's no sound. If the fuse is fine, check for voltage at the switch. If there's no voltage, check the wiring. If there's voltage, check the switch for continuity. If the switch is faulty, replace it. Check the ground connection and the wires at the mirror for voltage. If there's no voltage, check the wiring. If there's voltage, test the mirror off the vehicle. Replace if necessary.
Q: How to remove and install the mirror on Lincoln Town Car?
A: Remove the door trim panel and water-shield to access the electrical connector for the mirror, on 1997 and later models. For cable-operated mirrors, detach the control lever from the instrument panel or door and connect a string or thin wire to the control cable. Take away any holding clips, screws, and the mirror. Pull out the control cable from this door. The mirror screws are reachable from the outside on some models. Tie down the string or wire to the control end of new cable/mirror assembly, fix back this mirror with screws in place, and secure a cable. For electric mirrors, disconnect the cable from the negative battery terminal. Pry off the mirror access hole cover, remove the nuts, detach it from a door, and unplug an electrical connector. These actions are performed in reverse order during the installation.
