Parts
- Power mirror motor assembly × 1 — Use OEM specification for specific mirror type
- Door panel clips (if broken during removal) × 1 — Honda OEM door panel clip set
Preparation
- Park vehicle on level surface and engage parking brake
- Disconnect negative battery terminal using 10mm socket and wait 3 minutes before proceeding
- Lower the window approximately 4 inches to allow access to door panel fasteners
- Identify which mirror (driver or passenger) requires replacement
Procedure
- 1Remove door panel lower fastenersRemove the Phillips screw from the bottom rear corner of the door panel. Use panel removal tool to carefully pry out the lower trim panel securing clips along the bottom edge of the door panel. Start from the rear and work forward.
- 2Remove door handle and window switch assemblyInsert panel removal tool behind the window switch panel at the front edge. Carefully pry upward to release the clips. Disconnect the window switch connector by pressing the release tab and pulling straight up. Remove the Phillips screw behind the door handle trim. Pry the door handle trim away and disconnect the interior door handle cable by rotating it 90 degrees and unhooking.
- 3Remove door panelLocate and remove any remaining Phillips screws securing the door panel (typically one in the armrest area). Using panel removal tool, work around the perimeter of the door panel to release the retaining clips. Lift the door panel upward to disengage it from the window sill, then pull away from door. Rest the panel safely on a protected surface.
- 4Remove vapor barrier accessCarefully peel back the plastic vapor barrier sheet only in the area behind the mirror location. The barrier is typically held with butyl sealant. Peel back just enough to access the mirror mounting bolts and electrical connector—do not remove the entire barrier.ℹ️Preserve the vapor barrier integrity; it provides moisture protection for door components
- 5Disconnect mirror electrical connectorLocate the mirror wiring harness connector inside the door. Press the locking tab and disconnect the connector. If equipped with power folding mirrors, there will be an additional connector for the folding motor—disconnect both.
- 6Remove mirror assembly from doorLocate the three 10mm mounting bolts securing the mirror assembly to the door frame (accessible from inside the door). Remove all three bolts and carefully extract the mirror assembly from the outside of the door. Support the mirror from outside to prevent it from falling.⚠Have an assistant support the mirror from outside, or use tape to prevent it from falling when the last bolt is removed
- 7Separate mirror motor from housingWith mirror assembly on workbench, locate the screws or clips securing the motor assembly to the mirror housing. On most Accord mirrors, remove the three small Phillips screws on the back of the housing. Carefully separate the motor assembly from the mirror glass carrier. Note the orientation of the motor and any alignment pins.
- 8Install new mirror motorPosition the new mirror motor into the mirror housing, aligning any guide pins or mounting tabs. Ensure the motor drive mechanism properly engages with the mirror glass carrier. Install and tighten the retaining screws to secure the motor.
- 9Reinstall mirror assembly to doorFeed the mirror wiring harness through the door opening. Position the mirror assembly on the door and align the three mounting bolt holes. Install the three 10mm mounting bolts and torque to specification.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 10Reconnect electrical and testReconnect the mirror electrical connector(s) inside the door, ensuring they click into place. Temporarily reconnect the battery negative terminal and test mirror operation in all directions (up, down, left, right) using the mirror switch. If equipped, test power folding function. Disconnect battery again before continuing reassembly.Torque specBattery Terminal Bolts6 Nm (4 lb-ft)
- 11Reseal vapor barrierPress the vapor barrier sheet back into position, ensuring the butyl sealant adheres properly around all edges. Verify complete seal to prevent water intrusion into the door.
- 12Reinstall door panelReconnect the interior door handle cable by hooking it in place and rotating 90 degrees. Position door panel and engage the top edge over the window sill. Press firmly around the perimeter to seat all retaining clips. Reinstall all Phillips screws. Reconnect window switch harness and snap the switch panel into place. Install any remaining trim pieces.
- 13Final battery connectionReconnect the negative battery terminal and torque to specification. Reset the power window auto-up/down feature by fully lowering each window, then fully raising and holding the switch up for 2 seconds after the window closes.Torque specBattery Terminal Bolts6 Nm (4 lb-ft)
Reassembly
- Verify all door panel clips are properly seated and the panel is flush with the door frame
- Test all door panel switches and controls for proper operation
- Ensure door opens and closes smoothly without interference from the panel
Verification
- Test mirror adjustment in all four directions using the mirror control switch
- Verify mirror moves smoothly without binding or unusual noise
- If equipped with power folding, test the fold and unfold function completely
- Check that mirror holds position and does not drift after adjustment
- Verify heated mirror function if equipped by running defroster
