This procedure covers the removal and replacement of the rear power window motor on a 2014-2019 Toyota Corolla sedan.

Warnings

Tools required

Parts

• Rear power window motor × 1 — Use OEM specification
• Door panel clips (assorted) × 1 — Replace any broken clips

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery terminal and wait 3 minutes to allow capacitors to discharge
3. Roll rear window to approximately mid-height position before disconnecting battery if motor is functional
4. Prepare workspace inside vehicle by protecting seat with clean towel or seat cover

Procedure

1. 1

   Remove door panel trim components
   Remove the small triangular trim piece at the front corner of the door panel near the mirror. Use the flat blade trim tool to carefully pry it away from the door. Remove the screw cover behind the interior door handle and remove the Phillips screw securing the handle trim.
2. 2

   Remove door panel mounting screws
   Locate and remove all Phillips screws securing the door panel. There are typically two screws in the door pull/armrest area and one in the lower rear corner of the panel. Keep screws organized for reinstallation.
   Torque spec

   Cover Screws10 Nm (8 lb-ft)
3. 3

   Detach door panel clips
   Starting at the bottom rear corner, use the trim removal tool to gently pry the door panel away from the door frame. Work your way around the perimeter, releasing each plastic clip. Lift the panel upward to disengage it from the window sill channel, then pull it away from the door.
4. 4

   Disconnect electrical connectors
   Disconnect the electrical connector for the power window switch and any other connectors attached to the door panel (speaker, puddle light if equipped). Press the release tabs and pull connectors straight apart. Set the door panel aside in a safe location.
5. 5

   Remove moisture barrier
   Carefully peel back the plastic moisture barrier sheet to access the window regulator and motor assembly. Only remove as much as necessary to access the motor mounting bolts. Take care not to tear the barrier, as it provides critical water protection.
6. 6

   Support window glass
   Use painter's tape or masking tape to secure the window glass in the up position to the door frame. This prevents the glass from dropping when the regulator is disconnected. Ensure the glass is stable and well-supported before proceeding.
7. 7

   Disconnect window motor electrical connector
   Locate the power window motor electrical connector inside the door cavity. Press the release tab and disconnect the connector from the motor. Move the wiring harness aside to provide clear access to the motor mounting bolts.
8. 8

   Remove window motor mounting bolts
   Using a 10mm socket, remove the three bolts securing the window motor to the regulator assembly. The motor is typically mounted to the regulator mechanism in the lower portion of the door. Support the motor as you remove the final bolt to prevent it from falling.
   Torque spec

   Module Mounting Bolts8 Nm (6 lb-ft)
9. 9

   Extract window motor from door
   Carefully maneuver the window motor out of the door cavity through the access opening. The motor may need to be tilted or rotated to clear internal door structures. Inspect the regulator mechanism for damage or wear while the motor is removed.
10. 10

    Install new window motor
    Position the new window motor into the door cavity and align it with the mounting holes on the regulator assembly. Ensure any drive gears or cables are properly engaged with the regulator mechanism before securing the motor.
11. 11

    Secure motor mounting bolts
    Install the three mounting bolts and tighten them in a cross pattern to the specified torque of 26.0 Nm (19.0 lb-ft). Ensure the motor is seated flush against the regulator mounting surface before final tightening.
    Torque spec

    Module Mounting Bolts8 Nm (6 lb-ft)
12. 12

    Reconnect electrical connector
    Reconnect the electrical connector to the window motor. Ensure the connector clicks into place and is fully seated. Route the wiring harness to avoid pinch points or interference with moving components.
13. 13

    Test window operation
    Reconnect the negative battery terminal and torque to 6.0 Nm (4.0 lb-ft). Remove the tape securing the window glass. Test window operation using the switch before reinstalling the door panel. Verify smooth operation in both up and down directions through the full range of motion.
    Torque spec

    Battery Terminal Bolts6 Nm (4 lb-ft)
14. 14

    Reinstall moisture barrier and door panel
    Press the moisture barrier back into place, ensuring all edges are properly sealed. Reconnect all electrical connectors to the door panel. Align the door panel with the window sill channel and press firmly around the perimeter to engage all clips. Reinstall all mounting screws and trim pieces, torquing cover screws to 10.0 Nm (8.0 lb-ft).

    Cover Screws10 Nm (8 lb-ft)

Reassembly

1. Ensure all door panel clips are fully seated and the panel is secure before closing the door
2. Verify the moisture barrier is properly sealed to prevent water intrusion
3. Replace any broken or damaged door panel clips during reassembly

Verification

• Test window operation multiple times in both directions to confirm smooth movement
• Verify window reaches full up and down positions without binding or unusual noise
• Check that window auto-up/auto-down feature works if equipped (may require initialization procedure)
• Inspect door panel fit and ensure all clips are engaged with no rattles
• Confirm all electrical functions on the door panel work correctly (locks, switches)
