Steps
Remove the door panel
Release the handle bezel and lock connector, remove the pull screws and upper trim, then release the panel clips. Disconnect the handle rod and control panel, and peel back the water shield while preserving its seal.
Secure the glass and remove the regulator
Unbolt the glass from the regulator, raise it fully, and tape it to the frame. Unplug the motor, remove the regulator mounting bolts, and guide the assembly out through the door without scratching the glass.
Transfer the motor and mount the regulator
If needed, remove the motor screws and transfer the motor to the replacement regulator. Feed the new assembly through the opening, start its mounting bolts, reconnect the motor, and lower the glass carefully onto the regulator mounts.
Reinstall the panel and verify travel
Secure the glass to the regulator, remove the tape, and test the window before refitting trim. Restore the water shield, reconnect the lock, handle, and switch wiring, then hang the panel and reinstall its screws and clips.
Check your vehicle’s repair manual for exact specifications and fit.
