Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the fuse for the power windows.
Use a multimeter to test the fuse for continuity; replace if necessary.

3. Check Relay Operation

Locate the power window relay in the fuse box.
Remove the relay and visually inspect it for any damage.
Swap it with a similar relay to test functionality; replace if the windows work with the swapped relay.

4. Inspect Wiring and Connectors

Open the driver’s door and inspect the wiring harness running into the door.
Ensure all connectors are seated properly and check for any pinched or damaged wires.
Repair or replace any damaged wiring found during the inspection.

5. Reconnect Battery and Test Windows

Reconnect the negative battery terminal securely.
Test the power window switches to see if function is restored.
If necessary, perform a master reset by holding the window switch down for a few seconds after reconnecting the battery.
