Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical systems.

2. Fuse Inspection

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller.
Inspect the fuse for any signs of blowing; replace if necessary with the same amperage.

3. Switch Testing

Remove the door panel to access the power window switch.
Disconnect the switch connector and use a multimeter to check for voltage when the switch is pressed.
If no voltage is present, replace the switch.

4. Motor Testing

Remove the door panel and disconnect the motor's wiring harness.
Use jumper wires to connect the motor directly to the battery; ensure the motor operates smoothly.
If the motor does not function, replace the window motor.

5. Wiring Inspection

Visually inspect the wiring harness for any frays, corrosion, or other damage.
If damage is found, repair or replace the affected wiring.

6. Regulator Check

Inspect the window regulator for any physical obstructions or damage.
If the regulator is faulty, remove it and replace it with a new one.
