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

Warnings

Tools required

Parts

• Front power window regulator assembly × 1 — Use OEM specification
• Door panel trim clips (assorted) × 1 — GM replacement clip kit
• Vapor barrier adhesive (if damaged) × 1 — 3M window weld or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect 12V battery negative terminal to prevent electrical shorts and window operation during service
3. Lower window approximately halfway for easier access to regulator bolts (if window is functional)
4. Lay out protective cloth or blanket on work surface for door panel storage

Procedure

1. 1

   Remove door panel trim components
   Remove the power mirror switch bezel by carefully prying from the front edge. Disconnect the electrical connector. Remove the inner door handle trim cover by inserting a panel tool behind the rear edge and releasing the clips. Remove the door pull/armrest cover screw located under a small cover cap.
2. 2

   Remove door panel fasteners
   Remove all door panel mounting screws using a T20 Torx driver. There are typically 2-3 screws along the bottom edge of the door panel and one behind the door handle trim area. Keep screws organized for reinstallation.
3. 3

   Detach and remove door panel
   Lift the door panel upward to disengage it from the door's upper retaining channel. Pull the panel away from the door carefully to release the remaining trim clips. Disconnect all electrical connectors for window switches, lock switches, and any ambient lighting. Remove the door panel and set aside on protected surface.
4. 4

   Peel back vapor barrier
   Carefully peel back the plastic vapor barrier enough to access the window regulator assembly. Take care not to tear the barrier. If adhesive is compromised, have replacement adhesive ready for reassembly. Use masking tape to temporarily hold barrier out of the way.
5. 5

   Secure window glass
   Move the window glass to the full up position. Secure the glass in place using wide masking tape applied from the outside of the door, taping the glass to the door frame. This prevents the glass from falling when the regulator is detached.
6. 6

   Disconnect window motor electrical connector
   Locate the window motor electrical connector inside the door cavity. Press the release tab and disconnect the connector from the window motor. Ensure connector is positioned away from work area.
7. 7

   Detach glass from regulator
   Through the access holes in the door frame, locate the window glass attachment bolts that secure the glass to the regulator lift mechanism. Remove these bolts (typically 8mm or 10mm) and carefully separate the glass from the regulator. The glass should now be supported only by the tape applied earlier.

8. 8

   Remove regulator mounting fasteners
   Locate all regulator mounting fasteners (typically 3-4 bolts or rivets). If factory rivets are present, carefully drill them out using a 1/4 inch drill bit. If bolts are present, remove them using appropriate socket. Note the location of each fastener for proper replacement positioning.

9. 9

   Extract regulator assembly
   Carefully maneuver the window regulator assembly out through the main access opening in the door frame. The regulator may need to be rotated and angled to clear the door structure. Feed the motor and cable assembly through carefully to avoid snagging.
10. 10

    Install new regulator assembly
    Position the new regulator assembly into the door cavity, routing it through the access opening. Align the mounting holes with the door frame. If converting from rivets, use appropriate replacement bolts (typically M6 bolts). Install and hand-tighten all mounting bolts before final torquing.

    Attach glass to regulator
    Align the window glass channels with the regulator lift mechanism. Install the glass attachment bolts through the access holes and torque to specification. Ensure glass sits properly in the regulator mechanism before tightening.

    Connect electrical and test operation
    Reconnect the window motor electrical connector. Temporarily reconnect the 12V battery and test window operation through full up and down travel. Verify smooth operation without binding or unusual noises. Disconnect battery again before completing reassembly.

Reassembly

1. Remove tape securing the window glass
2. Reposition and re-adhere the vapor barrier, using fresh adhesive if original adhesive was damaged
3. Reconnect all door panel electrical connectors (window switches, lock switches, lighting)
4. Position door panel and engage upper retaining channel, then press firmly around perimeter to seat trim clips
5. Install door panel mounting screws with T20 Torx driver
6. Reinstall door handle trim cover, armrest cover, and power mirror switch bezel
7. Reconnect 12V battery negative terminal and torque to specification

Verification

• Test window operation through complete up and down travel multiple times, verifying smooth operation
• Verify window seals properly against weatherstripping when fully closed
• Check that window auto-up and auto-down features (if equipped) function correctly
• Verify all door panel trim pieces are secure with no rattles
• Test all door-mounted switches for proper operation
• Inspect door panel alignment and verify all clips are properly seated
