Check switch and fuse

Goal: Rule out a faulty switch or blown fuse.

  • Confirm the switch responds when pressed. Listen for a click or hum from the motor.
  • Locate the fuse box and check the sunroof fuse. Replace if blown with the same amperage.
  • Good: Switch works and fuse is intact. Proceed to Tracks and obstruction.
  • Bad: Fuse blown or switch faulty—replace and retest. If the fuse blows again, call a mechanic.

Tracks and obstruction

  • Inspect the tracks for leaves, dirt, or ice. Clean with a soft brush. Apply silicone-based lubricant if dry.
  • Press the switch and listen for the sunroof motor. If you hear it but the roof does not move, the cable or mechanism may be jammed or broken.
  • Good: Tracks are clear and the sunroof moves. If the motor runs but the roof is stuck, call a mechanic.
