Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked safely and turned off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace the Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Refer to the fuse diagram to identify the power window fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Inspect and Test the Window Switch

Remove the door panel to access the window switch assembly.
Disconnect the switch connector.
Use a multimeter to test for continuity across the switch terminals while pressing the switch. Replace the switch if it is faulty.

4. Test the Relay

Locate the power window relay in the fuse box.
Remove the relay and test it using a multimeter or swap it with a similar relay to see if operation resumes.
Replace the relay if it is found to be defective.

5. Check Wiring and Connections

Visually inspect the wiring harness for any frayed or damaged wires.
Ensure all connectors are securely attached.
Repair or replace any damaged wiring as necessary.

6. Test Window Motors

Remove the door panel to access the window motor.
Disconnect the motor connector.
Use jumper wires to connect the motor directly to the battery to test its operation.
Replace the motor if it does not operate when powered directly.
