- If the power mirror system fuse is open and a short to ground in the battery positive voltage circuit is not detected, the fault could be a short to ground in one of the power mirror control circuits. This would open the power mirror system fuse when the mirror switch is pressed.
- If both power mirrors are inoperative on one or more axis, the most probable cause is a power mirror switch failure. However the fault could be an open circuit on two or more of the power mirror control circuits.
- The power mirror assembly is equipped with a pigtail harness and is not serviceable. If an internal open or short is detected in the power mirror assembly, replace the power mirror assembly.
