Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the workspace is clear and safe.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).

Remove the door panel using a trim removal tool.
Disconnect the power window switch harness.
Replace the faulty switch with a new one.
Reconnect the harness and reassemble the door panel.

4. Inspect and Replace Window Motor/Regulator
