Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Tools Required: Socket set, multimeter, OBD-II scanner.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the fuse related to the power windows.
Inspect the fuse for continuity; replace if blown with the same amperage rating.
Reinstall the fuse box cover and reconnect the negative battery terminal.

3. Replace the Window Switch

Remove the door panel by unscrewing screws and gently prying it loose.
Disconnect the window switch harness from the back of the switch.
Replace the old switch with a new one, ensuring a secure connection.
Reassemble the door panel and test the window operation.

4. Inspect and Test the Window Motor

If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor's wiring harness.
Using a multimeter, check for voltage at the motor connector when the switch is pressed.
If no voltage is present, check wiring continuity; if voltage is present, replace the window motor.

5. Final Assembly

Once repairs are completed, reassemble any removed components and the door panel.
Ensure all screws are tightened and connections are secure.
