Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to avoid electrical shock.
Ensure the vehicle is in a secure position (parked on a level surface).

2. Fuse Inspection

Locate the fuse box (usually found in the glove compartment or under the dashboard).
Remove the relevant fuse for the power windows using a fuse puller.
Inspect the fuse for continuity and replace with a new fuse of the same amperage if blown.

3. Switch Testing

Remove the door panel to access the window switch assembly.
- Use a flathead screwdriver to gently pry off the panel clips.
- Unscrew any screws securing the door panel.
Disconnect the window switch connector.
Use a multimeter to test for continuity across the switch terminals.
Replace the switch if it fails the continuity test.

4. Wiring Inspection

Visually inspect the wiring harness in the driver's door for frayed wires or loose connections.
Repair or replace any damaged wiring as necessary.

5. Motor Testing

Disconnect the power window motor from the regulator.
Use jumper wires to connect the motor directly to a 12V power source.
If the motor does not operate, replace the window motor.

6. Regulator Inspection

If the motor is operational, inspect the window regulator for any mechanical binding or damage.
Replace the window regulator if any issues are found.
