Solution

1. Preparation

Gather necessary tools and parts.

2. Inspect and Clean Sunroof Tracks

Use a soft brush or cloth to remove any debris or dirt from the sunroof tracks.
Apply a silicone-based lubricant to the tracks to ensure smooth operation.

3. Check and Replace the Sunroof Fuse

Locate the fuse box (typically found in the glove compartment or under the dashboard).
Identify the sunroof fuse using the diagram and remove it.
Inspect the fuse for continuity; replace it if blown with one of the same rating.

4. Test and Replace the Sunroof Switch

Remove the sunroof switch from the overhead console using a trim removal tool.
Use a multimeter to test the switch for continuity; if faulty, replace with a new switch.
Reinstall the switch once testing is complete.

5. Inspect and Replace the Sunroof Motor

Remove the headliner if necessary to access the sunroof motor.
Disconnect the motor's wiring harness and remove the mounting screws.
Install the new motor by reversing the removal steps and ensure it is properly secured.

6. Alignment Adjustment

Manually close the sunroof to check for alignment issues.
If misaligned, adjust the mounting brackets of the sunroof panel to ensure proper fitment.
Test the sunroof to confirm that it opens and closes without obstruction.
