Mirrors, Power

Tools Required:

• Rotunda Digital Volt Ohmmeter 007-00001

Use the connector illustration, Switch Logic Table and the following procedures to diagnose concerns with the power mirror.

Both RH and LH Mirrors Do Not Operate

1. Check the 15 amp courtesy lamp fuse in the panel and replace if blown or damaged.

2. If fuse is OK, remove the switch assembly and check if power is available at the harness connector to the switch using an ohmmeter such as Rotunda Digital Volt Ohmmeter 007-00001 or equivalent across Circuits 54 (LG/Y) and 57 (BK).

3. If no power, check across Circuit 54 (LG/Y) to a known good ground.

4. Trace back through Circuit 54 (LG/Y) and correct the concern.

5. If power is OK across Circuits 54 (LG/Y) and 58 (BK), check if switch is damaged by jumping across appropriate circuits shown in Switch Logic Table.

6. If mirrors can be operated by bypassing switch as described in Step 5, then replace damaged switch.

Either RH or LH Mirror Does Not Operate

1. Remove the door trim panel and verify that the harness is connected to the mirror.

2. Using an ohmmeter check continuity of circuits in harness connector to the mirror by operating the switch.

3. If circuit check does not show continuity, trace circuit to connector in floor console.

4. If circuit continuity and logic is correct, replace the mirror assembly.

Either RH or LH Mirror Does Not Function or Functions at Variance With System Logic

1. Remove the front door trim panel on the vehicle side experiencing the malfunction.

2. Using an ohmmeter, verify circuit logic at the harness connector to the mirror with switch operation.

3. If OK, replace mirror.

4. If not OK, check if OK at switch connector.

5. If OK at switch, trace along harness to determine where the cross circuitry took place and correct.
