Function Test

1. Remove the driver's door switch trim (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).

   Courtesy of AMERICAN HONDA MOTOR CO., INC.

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.
   • Defogger doesn't work (Except '04 USA models), go to step 8.

   Both mirrors

4. Measure the voltage between the No. 6 terminal and body ground with the ignition switch ON (II). There should be battery voltage.
   • If there is no battery voltage, check for:
     • Blown No. 30 (7.5 A) fuse in the under-dash fuse/relay box.
     • An open in the BLK/YEL wire.
   • If there is battery voltage, go to step 5.
5. Check for continuity between the No. 3 terminal and body ground.

   There should be continuity.

   • If there is no continuity, check for:
     • An open in the BLK wire.
     • Poor ground (G601).
   • If there is continuity, check both mirrors individually as described in step 6 and 7.

   Left mirror

6. Connect the No. 6 terminal to the No. 9 terminal, and the No. 2 (or No. 10) terminal to the No. 3 terminal 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 GRN/WHT) 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, repair the BLU/BLK wire.
   • If the mirror works properly, check the mirror switch.

   Right mirror

7. Connect the No. 6 terminal to the No. 7 terminal, and the No. 1 (or No. 10) terminal to the No. 3 terminal with jumper wires. The right mirror should tilt down (or swing left) with the ignition switch ON (ID.
   • If the mirror does not tilt down (or does not swing left), check for an open in the WHT/RED (or GRN/WHT) 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, repair the RED/YEL wire.
   • If the mirror works properly, check the mirror switch.

   Defogger (Except '04 USA models)

8. Connect the No. 12 and No. 11 terminals with a jumper wire, and measure the voltage between the No. 2 terminal of the mirror connectors 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 BLK/YEL or ORN wire.
     • Blown No. 30 (7.5 A) fuse in the under-dash fuse/relay box.
   • If only one fails to warm up, check:
     • Its defogger.
     • Poor ground at G601 (left mirror) or G503 (right mirror).
   • If both warm up, check the defogger switch.

Power Mirror Switch Test/Replacement

1. Remove the driver's door switch trim (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
2. Disconnect the 13P connector (A) from the power mirror switch (B).

3. Check for continuity between the terminals in each switch position according to Fig. 5.

4. If the continuity is not as specified, replace the power mirror switch.

Power Mirror Actuator Test

1. Remove the door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
2. Disconnect the 13P connector (A) from the power mirror actuator (B).

3. Check actuator operation by connecting power and ground according to Fig. 8.

4. If the mirror fails to work properly, replace the mirror actuator.

   Defogger Test (Except '04 USA models)

5. Check for continuity between the No. 2 and No. 7 terminals of the 13P connector. There should be continuity with the defogger switch ON. If there is no continuity, check for an open circuit.

Power Mirror Actuator Replacement

1. Remove the mirror holder (see MIRROR HOLDER REPLACEMENT ), power mirror (see POWER MIRROR REPLACEMENT ), and disconnect the connector.
2. Cut the wire harness (A), tube (B) with a cutter, and remove the clip (C).

3. Remove the screw from the harness clip (D) and the gasket (E).
4. Remove the three screws, and separate the mirror housing (A) from the bracket (B).

7. Route the wire harness of the new actuator through the hole in the bracket and gasket.
8. Install the actuator, bracket, harness clip, and gasket in the reverse order of removal.
9. Install the new actuator terminals into the connector in the original arrangement as shown.
