Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the fuse for the power windows and inspect it visually; replace if blown with a new fuse of the same amperage.

3. Check Window Switches

Tools Required: Multimeter
Remove the door panel to access the window switch assembly.
Disconnect the switch connector and test for voltage at the switch terminals while pressing the button.
If no voltage is present, replace the switch with a new one.

4. Inspect Wiring Harness

Visually inspect the wiring harness for frayed or damaged wires.
Repair any damaged wires using electrical tape or replace the harness if necessary.

5. Test Power Window Motor

Tools Required: Multimeter, jumper wires
Disconnect the power window motor from the door panel.
Using jumper wires, connect the motor directly to the vehicle battery to see if it operates.
If the motor does not work, replace it with a new power window motor.

6. Reassemble Components

Reinstall the door panel carefully, ensuring all clips and screws are secured.
Reconnect the battery, and test the window operation.
