Power Mirrors Inoperative Aztek
Diagnostic Aids
| • | 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. |
Test Description
The numbers below refer to the step numbers on the diagnostic table.
-
This step tests the integrity of both the mirror control circuits and the power mirror switch. If both power mirrors are inoperative on one or more axis, begin testing by disconnecting one of the power mirrors, if an open circuit is detected and repaired for that power mirror, repeat step 6 for the other power mirror.
-
This step tests the integrity of the battery positive voltage circuit not the fuse.

Power Mirrors Inoperative Rendezvous w/A43
Diagnostic Aids
| • | An intermittent power mirrors inoperative fault may be caused by an open outside rearview mirror switch ground circuit. When the outside rearview mirror switch ground circuit is open, the switch may seek a ground path through the illumination ground circuit. |
| • | An intermittent driver outside rearview mirror malfunction may be caused by an open driver mirror motor left control circuit. When the driver mirror motor left control circuit is open, the driver mirror motor may seek an alternate circuit path through the passenger mirror motor. |
| • | An intermittent passenger outside rearview mirror malfunction may be caused by an open passenger mirror motor left control circuit. When the passenger mirror motor left control circuit is open, the passenger mirror motor may seek an alternate circuit path through the driver mirror motor. |
Test Description
-
Tests for an open in the outside rearview mirror switch ground circuit. If the mirror switch ground circuit is open, turning on the headlamps will remove the alternate ground path through the illumination ground circuit.
-
Tests to see if the malfunction is on the switch side of the MSM, or the mirror motor side.
-
Tests for a short to ground in the mirror switch or motor control circuits.
-
Tests for an open or short to ground in the mirror switch supply voltage circuit.
-
Tests for an open or short to ground in the mirror motor.
-
Tests for an open or short to ground in the mirror motor assembly.
