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