Solution

1. Preparation

Gather necessary tools: socket set, multimeter, OBD-II scanner, and screwdriver set.
Disconnect the vehicle battery to ensure safety while working on electrical systems.

2. Remove Door Panel

Unscrew any screws securing the door panel using a screwdriver.
Carefully pry off the door panel starting from the bottom using a trim removal tool.
Disconnect any electrical connectors for lights or switches attached to the door panel.

3. Inspect and Test Components

Check the power window switch for continuity using a multimeter. If faulty, replace the switch.
Inspect the wiring harness for frayed wires or loose connections. Repair as needed.
If the switch and wiring are functional, test the window motor by applying direct battery voltage to it. If it operates, the motor may need replacement.

4. Replace Faulty Components

If the window motor is found to be defective, remove it from the window regulator:
- Remove any retaining screws or clips securing the motor.
- Disconnect the wiring harness from the motor.
- Install the new motor by reversing the removal steps.
If the window regulator is damaged, replace it by:
- Detaching it from the door frame after removing any screws or clips.
- Installing the new regulator and securing it properly.

5. Reassemble Door Panel

Reconnect the electrical connectors and test the window operation before reassembling the panel.
Align the door panel and press it back into place, ensuring clips are secured.
Reinstall all screws that were removed.
