One Mirror Does Not Function

  1. Working underneath mirror, remove head of plastic rivet, using a 1/4" (6 mm) drill. Remove rivet stem remnants. Remove screw from cover, remove cover, and disconnect plug. Check function of mirror by connecting 12 volts to terminals of wire plug.
  2. Yellow and Green wires provide up-down movement; Black and White wires, right-left movement. If mirror does not function, replace motor drive. See Motor Drive Removal in this article. 
  3. If mirror functions when tested, but does not operate when connected to feed wire, remove left door panel. Test feed wire for continuity at switch plug. Then, apply 12 volts to feed wire. If mirror functions through feed wire, but fails to respond to switch operation, replace switch.
