This procedure covers removal and replacement of the rear power window motor on a 2018-2024 Toyota Camry with 2.5L I4 engine.

Warnings

Disconnecting the battery will reset radio presets and power window auto-up/down calibration
Support the window glass before disconnecting the motor to prevent glass from falling
ℹ️Work in temperatures above 50°F (10°C) to prevent door panel clips from breaking during removal

Tools required

10mm socket and ratchetEssential
Phillips screwdriverEssential
Flat blade trim removal toolEssential
Torque wrench (2-50 Nm range)Essential
Wire brush or sandpaper
Shop towels
Masking tape

Parts

  • Rear power window motor assembly × 1 — Use OEM specification
  • Door panel clips (if broken) × 1 — Use OEM specification

Preparation

  1. Park vehicle on level surface and engage parking brake
  2. Roll the affected rear window down approximately 6 inches for access to motor mounting bolts
  3. Gather all tools and new parts
  4. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge

Procedure

  1. 1
    Disconnect battery negative terminal
    Using a 10mm socket, loosen the negative battery terminal bolt. Remove the cable from the terminal and secure it away from the battery to prevent accidental reconnection. Wait 3 minutes before proceeding.
    Torque spec
    Battery Terminal Bolts6 Nm (4 lb-ft)
  2. 2
    Remove door panel trim pieces
    Remove the door pull handle cover by prying gently with a trim tool. Remove the Phillips screws behind the cover. Remove the small triangular trim piece at the front upper corner of the door panel by gently prying outward.
    Torque spec
    Cover Screws11 Nm (8 lb-ft)
  3. 3
    Remove door panel mounting screws
    Locate and remove all door panel mounting screws: one in the door pull recess, one behind the triangular trim piece, and one at the bottom rear of the panel. Keep screws organized for reinstallation.
    Torque spec
    Cover Screws11 Nm (8 lb-ft)
  4. 4
    Release door panel clips
    Starting at the bottom rear corner, use a trim removal tool to carefully pop the door panel clips free from the door frame. Work your way around the perimeter, releasing approximately 8-10 clips. Lift the panel upward to disengage the top edge from the door frame.
    Apply steady pressure when releasing clips to avoid breaking them
  5. 5
    Disconnect door panel electrical connectors
    Reach behind the door panel and disconnect the electrical connectors for the window switch and any other connected components. Press the locking tab while pulling the connector straight out. Set the door panel aside on a protected surface.
  6. 6
    Remove moisture barrier access
    Carefully peel back the plastic moisture barrier only in the area around the window motor, creating access to the motor mounting bolts. Use masking tape to hold the barrier out of the way. Do not completely remove the barrier unless necessary.
    ℹ️The moisture barrier must be properly resealed to prevent water intrusion
  7. 7
    Support window glass
    Raise the window glass to a comfortable working height (approximately halfway up). Secure the glass in place using masking tape by taping the glass to the door frame, or have an assistant hold the glass to prevent it from falling when the motor is disconnected.
    Failure to support the glass may result in it falling and breaking
  8. 8
    Disconnect window motor electrical connector
    Locate the window motor electrical connector inside the door. Press the locking tab and disconnect the connector from the motor. Move the wiring harness aside.
  9. 9
    Disconnect motor from window regulator
    Locate the connection between the window motor and the regulator mechanism. Remove the mounting bolts that secure the motor to the regulator assembly using a 10mm socket. There are typically 3 bolts securing the motor.
    Torque spec
    Module Mounting Bolts8 Nm (6 lb-ft)
  10. 10
    Remove window motor
    Carefully extract the window motor from the door through the service opening. Maneuver it past any obstructions and remove it completely from the door cavity. Compare the old motor with the new motor to verify correct replacement part.
  11. 11
    Install new window motor
    Position the new window motor into the door cavity and align it with the regulator mechanism mounting points. Ensure the motor gear properly engages with the regulator mechanism before installing mounting bolts.
  12. 12
    Secure motor to regulator
    Install the three mounting bolts that secure the motor to the regulator mechanism. Hand-tighten all bolts first to ensure proper alignment, then torque to specification using a torque wrench in a cross pattern.
    Ensure motor is properly aligned before final torquing to prevent binding
    Torque spec
    Module Mounting Bolts8 Nm (6 lb-ft)
  13. 13
    Reconnect electrical connector
    Connect the electrical connector to the new window motor. Ensure the connector locks fully into place with an audible click. Tug gently on the connector to verify it is secure.
  14. 14
    Test window operation
    Reconnect the battery negative terminal temporarily (hand-tight only) to test window operation. Remove tape supporting the glass. Test the window through several complete up and down cycles to verify smooth operation and proper motor function. Disconnect battery again for final assembly.
  15. 15
    Reinstall moisture barrier and door panel
    Press the moisture barrier back into place, ensuring it is properly sealed around all edges. Reconnect all door panel electrical connectors. Position the door panel, engage the top edge first, then press firmly around the perimeter to seat all clips. Reinstall all mounting screws and trim pieces, torquing screws to specification.
    Torque spec
    Cover Screws11 Nm (8 lb-ft)
  16. 16
    Final battery reconnection
    Reconnect the negative battery terminal and torque the terminal bolt to specification. Ensure the terminal is clean and makes solid contact.
    Torque spec
    Battery Terminal Bolts6 Nm (4 lb-ft)

Reassembly

  1. Torque all fasteners to specified values using a calibrated torque wrench
  2. Ensure all electrical connectors are fully seated and locked
  3. Verify moisture barrier is properly sealed to prevent water intrusion
  4. Check that all door panel clips are fully engaged before driving

Verification

  • Test window operation through multiple complete cycles to verify smooth operation
  • Verify window auto-up and auto-down features work correctly (may need recalibration)
  • Check for any unusual noises during window operation
  • Verify door panel is secure with no rattles or loose sections
  • Test window one-touch auto features by resetting: roll window fully down, hold switch down for 2 seconds, then roll fully up and hold switch up for 2 seconds
