Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shocks.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover.
Use a fuse puller or pliers to remove the fuse and inspect it. Replace if blown (use the same amperage).

3. Inspect and Replace Window Switch

Remove the door panel using a trim removal tool; be cautious not to damage clips.
Disconnect the electrical connector from the window switch.
Test the switch with a multimeter for continuity; replace it if defective.
Reconnect the new switch and reassemble the door panel.

4. Test Window Motor Functionality

Remove the door panel to access the window motor.
Disconnect the motor's electrical connector.
Use jumper wires to connect the motor directly to the battery to see if it operates. If the motor does not run, replace it.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness for any signs of fraying or damage.
Clean and reconnect any corroded or loose connectors.
Repair or replace damaged wiring as necessary.
