Step 1: Diagnose the Problem

Before you start repairing, it’s crucial to identify the problem:

  1. Check the fuse: The issue might be as simple as a blown fuse. Refer to your car's manual to locate the fuse box and find the sunroof fuse. If it's blown, replace it and try operating the sunroof again.
  2. Listen for motor noise: If the fuse is intact, try operating the sunroof and listen for motor noise. If there's no sound, the motor might be the problem.

Step 2: Remove the Sunroof

Before removing the sunroof, ensure the glass is fully closed to prevent damage. To remove the sunroof:

  1. Remove the sunroof switch panel.
  2. Remove the sunroof glass.
  3. Disconnect the wiring harness from the motor.

Step 3: Check the Motor

Use your multi-meter to test the motor:

  1. Set your multi-meter to the DC voltage setting.
  2. Connect the meter's probes to the motor's power connector.
  3. Try operating the sunroof.
  4. If the meter shows no voltage, the issue might not be the motor but the power supply.

Step 4: Replace the Motor

If the motor is indeed the problem, you'll need to replace it:

  1. Remove the old motor by unscrewing it from its mounting bracket.
  2. Install the new motor and secure it with the screws.
  3. Reconnect the wiring harness.
