Power Mirrors

POWER MIRRORS

For complete circuit diagrams, refer to the appropriate wiring information.

1. Check the fuses in the Integrated Power Module (IPM). If OK, go to 2. If not OK, repair the shorted circuit or component as required and replace the faulty fuse(s).
2. Check for battery voltage at the fuse in the IPM. If OK, go to 3. If not OK, repair the open circuit to the IPM as required.
3. Disconnect and isolate the battery negative cable. Remove the wire harness connector from the power mirror switch. Connect the battery negative cable. Check for battery voltage at the fused B(+) circuit cavity in the door wire harness half of the power mirror switch wire harness connector. If OK, go to 4. If not OK, repair the open circuit to the IPM as required.
4. Disconnect and isolate the battery negative cable. Check for continuity between the ground circuit cavity in the door wire harness half of the power mirror switch wire harness connector and a good ground. There should be continuity. If OK, Testing and Inspection. If not OK, repair open in the ground circuit.
