Solution

1. Preparation

Gather tools: screwdriver set, socket set, trim removal tools, multimeter, and safety glasses.
Disconnect the vehicle battery to prevent electrical shock.

2. Remove Door Panel

Use a trim removal tool to carefully pry off the door panel clips.
Unscrew any screws securing the door panel (typically found near the handle and bottom of the panel).
Gently lift the panel off, ensuring not to damage any wiring connectors.

3. Inspect and Remove Window Regulator

Locate the window regulator and motor assembly.
Disconnect the wiring harness from the motor.
Remove the bolts securing the regulator and motor to the door frame using a socket set.
Carefully slide the window regulator assembly out of the door.

4. Replace or Repair Components

If the window regulator is damaged, replace it with a new one.
Clean any debris from the window track and lubricate it with silicone grease.
If the motor is faulty, replace it as well. Install the new motor according to the manufacturer’s instructions.

5. Reassemble Door Panel

Reinstall the window regulator and motor, ensuring all bolts are tightened to the manufacturer's specifications (typically around 7-10 Nm).
Reconnect the wiring harness to the motor.
Replace the door panel, ensuring all clips are secured and screws are tightened.

6. Final Checks

Reconnect the battery and test the window operation.
Ensure the window rolls up and down smoothly without grinding.
