Solution
1. Preparation
  • Tools Required: Screwdrivers, OBD-II scanner, multimeter, socket set
  • Disconnect the vehicle battery to ensure safety while working on electrical components.
2. Remove the Sunroof Switch
  • Use a flathead screwdriver to gently pry off the sunroof switch cover.
  • Unscrew the switch from its mounting location and disconnect the wiring harness.
  • Safety Warning: Ensure the battery is disconnected to avoid shorts.
3. Inspect and Test the Sunroof Motor
  • Locate the sunroof motor, typically found above the headliner in the front.
  • Check for any signs of damage or corrosion on the motor and connectors.
  • Use a multimeter to measure voltage at the motor’s connector while activating the switch.
    • Expected voltage: 12V when switch is pressed.
  • If no voltage is detected, trace the wiring back to the switch and relay for faults.
4. Check the Sunroof Track
  • Manually inspect the sunroof track for any debris or obstructions.
  • Clean the track using a soft cloth and lubricant specifically designed for sunroof tracks.
  • Ensure that the sunroof glass is properly aligned and not skewed.
5. Replace Faulty Components
  • If the motor or relay is faulty, replace them:
    • Remove the motor by unscrewing it from its mount and disconnecting the wiring.
    • Install the new motor or relay in reverse order, ensuring all connections are secure.
  • Reconnect the sunroof switch and test operation before reassembling the headliner.
