Remove the bolts securing the window regulator to the door frame using a socket set.
Install the new window regulator by reversing the removal steps, ensuring to secure it tightly.

4. Test and Reinstall Components

Reconnect the window motor and window switch to test functionality before fully reassembling the door panel.
If the window operates correctly, proceed to reattach the door panel.
Reconnect any electrical connectors, position the door panel back onto the door, and press it into place.
Reinstall screws and ensure all clips are secured.

5. Finalize and Reconnect Battery

Reconnect the vehicle’s battery after all components are securely in place.
Test the window operation again to confirm the issue is resolved.
