Heated Element: Testing and Inspection

Function Test




1. Remove the driver's door switch trim.
2. Disconnect the 13P connector (A) from the power mirror switch (B), and inspect the terminals. If OK, go to step 3.
3. Choose the appropriate test based on the symptom:
- Both mirrors don't work, go to step 4.
- Left mirror doesn't work, go to step 6.
- Right mirror doesn't work, go to step 7.
- Defoggers don't work, go to step 8.

Both mirrors

4. Reconnect the power mirror switch connector, and check for voltage between the No. 2 terminal and body ground with the ignition switch ON (II) while operating the power mirror switch. There should be battery voltage.
- If there is no battery voltage, check for:
- Blown No. 4 (7.5 A) fuse in the driver's under-dash fuse/relay box.
- An open in the ORN wire.
- If there is battery voltage, go to step 5.

5. Check for voltage between the No. 6 terminal and body ground while operating the power mirror switch. There should be less than 1 V.
- If there is more than 1 V, check for:
- An open in the BLK wire.
- Poor ground(G601).
- If there is less than 1 V, check both mirrors individually as described in the step 6 to 8.

Left mirror

6. Connect the No. 2 terminal to the No. 10 terminal, and the No. 5 (or No. 12) terminal to body ground with jumper wires. The left mirror should tilt down (or swing left) with the ignition switch ON (II).
- If the mirror does not tilt down (or does not swing left), check for an open in the BLU/WHT (or BLU/ORN) wire between the left mirror and the 13P connector. If the wire is OK, check the left mirror actuator.
- If the mirror neither tilts down (nor swings left) check for an open in the BLU/GRN wire.
- If the mirror works properly, check the mirror switch.

Right mirror

7. Connect the No. 2 terminal to the No. 11 terminal, and the No. 5 (or No. 13) terminal to body ground with jumper wires. The right mirror should tilt down (or swing left) with the ignition switch ON (II).
- If the mirror does not tilt down (or does not swing left), check for an open in the BLU/WHT (or LT GRN) wire between the right mirror and the 13P connector. If the wire is OK, check the right mirror actuator.
- If the mirror neither tilts down (nor swings left) check for an open in the YEL/WHT wire.
- If the mirror works properly, check the mirror switch.

Defogger

8. Connect the No. 1 and No. 8 terminals with a jumper wire, and check for voltage between the No. 8 terminal and body ground. There should be battery voltage and both mirrors should warm up with the ignition switch ON (II).
- If there is no voltage or neither warms up, check for:
- An open in the ORN and ORN/WHT wires.
- Blown No. 4 (7.5 A) fuse in the driver's under-dash fuse/relay box.
- Poor ground (G601, G651).
- If only one fails to warm up, check its defogger.
- If both warm up, check the defogger switch.
