This procedure covers the removal and replacement of the front power window motor on a 2023 Chevrolet Bolt EUV, including door panel removal and regulator disconnection.

Warnings

Tools required

Parts

• Power window motor assembly × 1 — Use OEM specification
• Door panel clips (assorted) × 1 — Replacement clip kit recommended

Preparation

1. Park the vehicle on a level surface and engage the parking brake
2. Disconnect the negative terminal of the 12V battery located in the rear cargo area and wait 2 minutes for system capacitors to discharge
3. Roll the affected window to the full up position before disconnecting power
4. Remove any personal items from the door pocket and armrest storage
5. Photograph electrical connector positions for reference during reassembly

Procedure

1. 1

   Remove door panel fasteners
   Remove the door pull handle cover by gently prying from the rear edge. Remove the T20 Torx screw behind the handle. Remove the small cover at the front edge of the door panel near the mirror triangle and remove the screw underneath. Locate and remove any additional screws along the bottom edge of the door panel.
2. 2

   Disconnect door panel electrical connectors
   Press the lock tab and disconnect the window switch connector. Disconnect any additional connectors for power mirror controls, ambient lighting, or speaker connections. Ensure all wiring is free before attempting to remove the panel.
3. 3

   Release door panel clips and remove panel
   Starting at the bottom rear corner, use a panel removal tool to gently release the retaining clips around the perimeter of the door panel. Work your way around the panel, supporting it as clips release. Once all clips are released, lift the panel upward to disengage it from the window sill and carefully remove it from the door. Set aside on a protected surface.
4. 4

   Remove vapor barrier access
   Carefully peel back the plastic vapor barrier sheet only in the area necessary to access the window motor. Use masking tape to secure the barrier edges to prevent tearing. Ensure you maintain a seal by not over-peeling the barrier.
5. 5

   Support window glass
   With the window in the full up position, secure it in place using masking tape from the glass to the door frame exterior, or use a window wedge. This prevents the glass from dropping when the regulator is disconnected.
6. 6

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door. Press the connector lock tab and disconnect the wiring harness from the motor. Ensure the connector is clean and free of corrosion.
7. 7

   Remove window motor mounting fasteners
   Locate the window motor mounting bolts securing the motor to the regulator assembly and door structure. Remove the mounting bolts using a 10mm socket. Support the motor as you remove the final bolt to prevent it from falling.

8. 8

   Extract window motor from door
   Carefully maneuver the window motor assembly through the access hole in the door frame. The motor may need to be rotated or tilted to clear obstructions. Take care not to damage the vapor barrier or wiring harness during extraction.
9. 9

   Prepare and install new window motor
   Compare the old and new motors to ensure correct fitment. Transfer any brackets or hardware if necessary. Apply a small amount of dielectric grease to the electrical connector on the new motor. Insert the new motor through the door access hole and align it with the mounting points on the regulator and door structure.
10. 10

    Install and torque motor mounting bolts
    Install the mounting bolts finger-tight to ensure proper alignment. Torque the mounting bolts to specification in a cross-pattern to ensure even seating of the motor against the mounting surface.

    Reconnect electrical connector and test
    Connect the electrical harness to the window motor, ensuring the connector locks securely. Temporarily reconnect the 12V battery and test window operation through full up and down cycles. Verify smooth operation without binding or unusual noise. Disconnect battery again before continuing.
12. 12

    Reinstall vapor barrier and door panel
    Carefully reposition the vapor barrier, ensuring a complete seal around all edges. Press firmly to re-adhere the barrier to the door. Replace any torn sections if necessary. Reconnect all door panel electrical connectors. Position the door panel onto the window sill and press firmly around the perimeter to engage all clips. Reinstall all screws and covers removed during disassembly.

Reassembly

1. Ensure all door panel clips are fully seated before reinstalling screws
2. Verify the vapor barrier is properly sealed to prevent water intrusion and wind noise
3. Reconnect the 12V battery negative terminal using the specified torque value

Verification

• With the ignition on, operate the window through multiple full up and down cycles from both the driver and door-mounted switches
• Verify the window operates smoothly without hesitation, binding, or unusual noise throughout its entire range of travel
• Check that the window auto-up and auto-down features function correctly if equipped
• Ensure the window fully seats at the top position and aligns properly with adjacent windows
• Verify all door panel clips are secure and there are no rattles or loose trim pieces
• Check for proper operation of all switches and features on the door panel
