Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to avoid electrical shock.
Ensure the vehicle is parked on a level surface.

2. Inspect and Clean the Window Switch

Remove the door panel using a trim removal tool.
Disconnect the window switch connector.
Clean the switch terminals with electrical cleaner.
Reconnect and test the switch functionality.

3. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse associated with the power windows as per the owner's manual.
Remove the fuse and inspect it visually; replace if blown.
Reinstall the fuse and test the window operation.

4. Test and Replace the Window Motor

Disconnect the window motor connector.
Use a multimeter to check for voltage at the connector when the switch is activated.
If voltage is present but the motor does not operate, remove the motor from the door.
Test the motor by connecting it directly to a 12V battery. Replace the motor if it fails to operate.

5. Reassemble the Door

Ensure all components are reinstalled securely.
Reattach the door panel, ensuring all clips and screws are properly fastened.
Reconnect the vehicle battery.
