Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a replacement fuse if necessary.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Refer to the owner's manual for the specific location of the power window fuse.
Remove the fuse and inspect it for continuity using a multimeter.
- If blown: Replace with a fuse of the same amperage rating (usually 15A or 20A).

3. Test Window Switches

Remove the door panel to access the window switch assembly.
Disconnect the switch connector and use a multimeter to test for continuity:
- Press each switch and confirm continuity across the correct terminals.
If a switch is faulty, replace it with a new one.

4. Inspect Wiring Harness

Visually inspect the wiring harness connected to the window motor and switches for any signs of wear, fraying, or disconnection.
Repair any damaged wires by splicing in new wire or using electrical tape for minor issues.

5. Test Window Motor

If the switches are functional, test the window motor:
- Remove the motor from the door panel and connect it directly to a 12V battery.
- Observe if the motor operates; if it does not, the motor may need to be replaced.

6. Reassemble Components

If all components are functioning, reassemble the door panel and ensure all clips are securely fastened.
Reconnect the vehicle battery.
