Test Description
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
The numbers below refer to the step numbers on the diagnostic table.
- 5: This step tests the integrity of both the mirror control circuits to the power mirror motor and the power mirror switch. If both power mirror motors are inoperative on one or more axis, begin testing by disconnecting one of the power mirror motors, if an open circuit is detected and repaired for that power mirror motor, repeat step 5 for the other power mirror motor.
- 7: This step tests the integrity of both the mirror control circuits to the power mirror assembly and the power mirror switch. If both power mirror assemblies are inoperative on one or more axis, begin testing by disconnecting one of the power mirror assemblies, if an open circuit is detected and repaired for that power mirror assembly, repeat step 7 for the other power mirror assembly.
- 8: This step tests the integrity of the battery positive voltage circuit not the fuse.
