Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Multimeter
- Socket set
- Screwdrivers
- Wire connectors (if needed)
Safety Warnings: Disconnect the battery before starting to prevent electrical shock and accidental window movement.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse based on the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and visually inspect it for damage.
Replace the fuse with one of the same amperage if it is blown.

3. Test Power Window Switches

Remove the door panel using a socket set and screwdriver to access the power window switches.
Disconnect the switch harness and use a multimeter to check for continuity when the switch is pressed.
If the switch is faulty, replace it with a new one by reconnecting the harness and reinstalling the door panel.

4. Inspect Wiring and Connectors

While the door panel is removed, visually inspect the wiring harness for any frays, cuts, or corrosion.
Repair or replace any damaged wiring or connectors.

5. Test Power Window Motor

Disconnect the power window motor from the window regulator.
Use jumper wires to connect the motor directly to the vehicle battery to check for operation.
If the motor does not work, replace the motor.

6. Replace Window Regulator if Necessary

If the motor operates but the window does not move, the window regulator may be faulty.
Remove the window regulator by unbolting it from the door frame and disconnecting it from the window.
Install the new regulator by reversing the removal process and ensure it is securely bolted.
