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

Warnings

Tools required

Parts

• Rear window motor and regulator assembly × 1 — Use OEM specification
• Door panel clips (assorted) × 1 — Replacement for any broken clips
• Vapor barrier adhesive × 1 — If vapor barrier is damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Ensure rear window is fully closed before beginning work
3. Open the rear door you will be working on and lower the front windows to prevent accidental lockout
4. Disconnect the negative battery terminal and wait 3 minutes for any residual power to dissipate
5. Gather all tools and new parts before beginning disassembly

Procedure

1. 1

   Remove rear door panel
   Use a Phillips screwdriver to remove the screw behind the interior door handle trim. Remove the small cover behind the door pull handle and remove the Phillips screw underneath. Use a trim tool to carefully pry around the perimeter of the door panel to release the retaining clips, working from bottom to top. Lift the door panel up and away from the door frame once all clips are released. Disconnect any electrical connectors for door switches or courtesy lights.
2. 2

   Remove vapor barrier
   Carefully peel back the plastic vapor barrier from the door frame. The barrier is typically held in place with adhesive butyl tape. Work slowly to avoid tearing the barrier. If access to the regulator mounting area is sufficient, you may only need to peel back a portion of the barrier rather than removing it entirely. Set aside for reinstallation.
3. 3

   Secure window glass in up position
   Roll the window up to the fully closed position if not already done. Use masking tape to secure the window glass to the door frame at the top, taping from the glass to the exterior door panel. This will prevent the glass from falling into the door cavity when the regulator is disconnected. Apply tape in at least two locations across the width of the window.
4. 4

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door cavity. Press the locking tab and pull the connector straight away from the motor. Note the routing of the wiring harness for proper reinstallation.
5. 5

   Disconnect glass from regulator
   Locate the two bolts that attach the window glass to the regulator lift channel. These are typically accessed through service holes in the door frame. Use a 10mm socket to remove both bolts. Carefully separate the glass from the regulator mounting bracket. Ensure the window is still securely taped in the up position.
6. 6

   Remove regulator mounting bolts
   Locate all regulator mounting bolts inside the door frame. There are typically 4-6 mounting bolts securing the regulator assembly to the door. Use a 10mm socket to remove all mounting bolts. Keep track of bolt locations as some may be different lengths. Support the regulator assembly as you remove the final bolts to prevent it from falling.
7. 7

   Remove regulator and motor assembly
   Carefully maneuver the window regulator and motor assembly out through the large service opening in the door frame. You may need to angle and rotate the assembly to clear the door frame and internal structures. The regulator arms will need to be positioned carefully to pass through the opening. Remove the assembly from the door.
8. 8

   Install new regulator and motor assembly
   Position the new window regulator and motor assembly near the door opening. Carefully insert the assembly through the service opening, angling and rotating as needed to clear internal door structures. Guide the regulator into position, aligning the mounting holes with the door frame. Thread in all mounting bolts by hand first to ensure proper alignment before tightening any bolts.
9. 9

   Torque regulator mounting bolts
   Using a torque wrench and 10mm socket, torque all regulator mounting bolts to specification in a cross-pattern sequence. Ensure the regulator assembly is properly seated against the door frame before final torquing. Verify all bolts are secure.

10. 10

    Reconnect glass to regulator
    Align the window glass mounting brackets with the regulator lift channel. Insert and hand-thread both mounting bolts. Ensure proper alignment before torquing. Once aligned, torque the glass mounting bolts to specification using a 10mm socket and torque wrench.

11. 11

    Reconnect electrical connector and test operation
    Reconnect the window motor electrical connector, ensuring it clicks into place securely. Reconnect the negative battery terminal and torque to specification. Before reinstalling the door panel, test the window operation through several full up and down cycles. Verify smooth operation with no binding or unusual noises. Check that the window seats properly against the weatherstrip when fully closed.

    Reinstall vapor barrier
    Remove the masking tape securing the window glass. Press the vapor barrier back into position, ensuring it adheres properly to the door frame. If the adhesive is insufficient, apply new butyl tape or vapor barrier adhesive to ensure a proper seal. The barrier must seal completely to prevent water intrusion and wind noise.
13. 13

    Reinstall door panel
    Reconnect any electrical connectors for door switches and courtesy lights. Position the door panel over the door frame, ensuring the top edge engages with the window channel properly. Press firmly around the perimeter to seat all retaining clips. Reinstall all Phillips screws, including those behind the door handle and pull handle. Replace any trim covers removed during disassembly.

Reassembly

1. Verify all electrical connectors are securely fastened before closing door panel
2. Replace any broken door panel clips with new ones to ensure proper panel retention
3. Test window operation multiple times before declaring job complete
4. Verify window auto-up and auto-down functions work correctly if equipped
5. Check for proper window alignment and sealing against weatherstrip

Verification

• Operate the rear window through multiple complete cycles to verify smooth operation
• Test window auto-up and auto-down features if equipped by briefly pressing the switch
• Listen for any unusual noises during window operation
• Verify window closes completely and seals properly against weatherstrip
• Check that door panel is secure with no rattles or loose clips
• Confirm all door switches and controls function normally
• Reset radio presets and clock as needed
