Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal.

2. Remove the Door Panel

Remove the screws securing the door panel (usually located near the handle and along the bottom edge).
Carefully pry off the door panel using a trim removal tool, starting from the bottom and moving upward to detach the clips.
Disconnect any electrical connectors for switches and speakers.

3. Inspect and Test Components

Locate the window motor and switch.
Check the window motor for any visible damage or corrosion.
If necessary, replace the window motor:
- Disconnect the motor's electrical connector.
- Remove the retaining bolts using a socket set.
- Carefully remove the motor from the regulator assembly.
If the switch is faulty, remove it by prying it out of the door panel and replacing it with a new one.

4. Reassemble and Test

Reinstall the new window motor or switch, ensuring all connections are secure.
Reattach the door panel by aligning it with the clips and pressing it back into place.
Reinsert the screws and reconnect any electrical connectors.
Reconnect the negative battery terminal.
