Solution

1. Preparation

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

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse associated with the power windows using the fuse diagram.
Remove the fuse using a fuse puller and inspect for a break in the filament.
Replace with a new fuse of the same amperage.

3. Check Window Switch

Remove the door panel to access the window switch.
Disconnect the switch connector and inspect for corrosion or damage.
Use a multimeter to test continuity across the switch terminals when pressed.
If faulty, replace the switch with a new one.

4. Inspect Wiring and Motor

With the door panel removed, check the wiring harness leading to the window motor for signs of wear or disconnection.
If no visible issues are found, connect the window motor directly to a power source to test its operation.
If the motor does not operate, replace it with a new window motor.

5. Reassemble Components

Reinstall the door panel securely, ensuring all clips and screws are properly fastened.
Reconnect the vehicle's battery.
