Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical issues.

Tools Required:

Flathead screwdriver
Phillips screwdriver
Torque wrench
Multimeter
Water source (e.g., pitcher or hose)

2. Inspect and Clean the Sunroof Seal

Use a flathead screwdriver to gently pry off any trim pieces around the sunroof if necessary.
Wipe down the sunroof seal with a damp cloth to remove debris and dirt.
Inspect the seal for cracks or tears. If damaged, proceed to seal replacement.

3. Clear Drainage Tubes

Locate the drainage tubes typically found in the front corners of the sunroof frame.
Use a flexible wire or compressed air to clear any blockages in the drainage tubes.
Test the drainage by pouring water into the sunroof channels and ensuring it flows out of the tubes underneath the vehicle.

4. Adjust Sunroof Alignment

If the sunroof is misaligned, remove the screws securing the sunroof mechanism using a Phillips screwdriver.
Adjust the sunroof position until it aligns correctly with the roof.
Re-secure the screws and ensure the sunroof closes completely without gaps.

5. Reassemble and Test

Replace any trim pieces removed for inspection.
Reconnect the battery and test the sunroof operation to ensure it opens and closes smoothly.
Conduct a water test by simulating rain or spraying water over the sunroof to verify no leaks occur.
