Solution

1. Preparation

Gather all necessary tools and replacement parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure a clean workspace to prevent dirt from entering the door assembly.

2. Remove Door Panel

Use a trim removal tool to carefully pry off the door panel clips.
Remove screws securing the door panel (typically found near the handle and bottom edge).
Disconnect any electrical connectors (e.g., for window switches and speakers).
Gently lift the door panel off and set it aside.

3. Remove Old Window Regulator

Locate the window regulator assembly inside the door.
Disconnect the window glass from the regulator by removing the clips or bolts holding it in place.
Support the window glass temporarily with tape to prevent it from dropping.
Remove any bolts securing the window regulator to the door frame.
Carefully slide the old regulator out of the door.

4. Install New Window Regulator

Position the new window regulator inside the door and secure it with the appropriate bolts.
Reconnect the window glass to the new regulator using the clips or bolts.
Ensure the regulator moves freely by operating it manually before reassembly.

5. Reassemble Door Panel

Reconnect all electrical connectors to the door panel.
Align the door panel and press it back into place, ensuring all clips are engaged.
Reinstall screws to secure the door panel.
Reconnect the vehicle battery.
