Testing

1. Check the fuses in the Power Distribution Center (PDC) and the fuseblock module. If OK, go to Step 2. If not OK, replace the faulty fuse(s).
2. Check for battery voltage at the fuse in the fuseblock module. If OK, go to Step 3. If not OK, repair the open circuit to the PDC as required.
3. Remove the power mirror switch as described.
4. Unplug the wire harness connector from the switch. Check for battery voltage at the fused B(+) circuit cavity of the switch wire harness connector. If OK, go to Step 5. If not OK, repair the open circuit to the fuseblock module as required.
5. Check for continuity between the ground circuit cavity of the switch wire harness connector and a good ground. There should be continuity If OK, go to Step 6. If not OK, repair the circuit to ground as required.

Power Mirror Switch Continuity:

6. Check the switch continuity. If OK, go to Step 7. If not OK, replace the faulty switch.

Power Mirror Test:

7. Use two jumper wires, one connected to a 12-volt battery feed, and the other connected to a good body ground. See the Power Mirror Test chart for the correct jumper wire connections at the power mirror switch wire harness connector (wire harness side, not switch side). If the mirror(s) don't respond as indicated in the chart, remove the mirror as described and check those circuits between the mirror and the switch for a short or open. If not OK, repair the circuits as required. If the circuits are OK, replace the faulty power outside mirror assembly.
