Solution

1. Preparation

Gather necessary tools: socket set, multimeter, flat-head screwdriver, Phillips screwdriver, and a door panel removal tool.
Disconnect the vehicle battery to prevent electrical shock.

2. Remove the Door Panel

Use a flat-head screwdriver to gently pry off any trim pieces covering the door panel screws.
Remove screws using a Phillips screwdriver.
Carefully detach the door panel from the door frame, starting from the bottom and working your way up.
Disconnect any electrical connectors for lights or switches attached to the door panel.

3. Inspect and Test Components

Window Switch: Disconnect the switch connector and test the switch with a multimeter for continuity.
Window Motor: Disconnect the motor connector and test it by applying direct battery voltage (positive to the motor terminal and ground to the negative terminal). If the motor does not operate, it may need replacement.
Wiring Harness: Check for any damaged wires or loose connections; repair or replace as necessary.

4. Replace Faulty Components

If the window motor is faulty, remove the old motor by unscrewing it from the regulator and install the new motor.
If the window regulator is damaged, remove it by unscrewing it from the door and replace it with a new unit.

5. Reassemble Door Panel

Reconnect any electrical connectors for the switch and window motor.
Position the door panel back onto the door frame and press it into place.
Reinstall screws and trim pieces removed during disassembly.
Reconnect the vehicle battery.
