Solution

1. Preparation

Tools Required:
- Multimeter
- Flathead screwdriver
- Torx screwdriver set
- Wire connectors (if needed)
Disconnect the negative terminal of the battery for safety.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the power window fuse using pliers.
Check the fuse visually or with a multimeter; replace it if blown (typically a 30A fuse).

3. Test and Replace Power Window Switch

Remove the door panel using a flathead screwdriver and Torx screws.
Disconnect the switch connector and use a multimeter to check for continuity across the terminals.
If the switch is faulty, replace it with a new one.

4. Test the Window Motor

With the door panel still removed, disconnect the window motor connector.
Use jumper wires to connect the motor directly to the battery (positive to positive, negative to negative).
If the motor doesn’t operate, replace it with a new motor.

5. Reassemble Components

Reconnect all wiring harnesses and secure the window motor.
Reinstall the door panel and ensure all clips and screws are tightened properly.
Reconnect the negative battery terminal.
