Solution

1. Preparation

Gather required tools and parts.
Disconnect the vehicle battery to prevent any electrical shorts.
Ensure the vehicle is parked on a flat surface.

2. Inspect and Replace Seals

Sub-steps:
1. Use a trim removal tool to carefully detach the sunroof trim.
2. Inspect the rubber seals around the sunroof for cracks, tears, or deformation.
3. If damaged, remove the old seals by carefully pulling them from their grooves.
4. Clean the surface of the sunroof frame with isopropyl alcohol to remove any debris.
5. Install new seals by pressing them firmly into place, ensuring they fit snugly.

3. Clear Drainage System

Sub-steps:
1. Locate the drainage tubes at each corner of the sunroof.
2. Use a compressed air canister to blow out any debris or clogs in the tubes.
3. Test the drainage by pouring water into the sunroof channel and ensuring it drains out the bottom of the vehicle.
4. If necessary, use a flexible wire to dislodge stubborn blockages.

4. Realign Sunroof

Sub-steps:
1. Check the alignment of the sunroof by ensuring it sits evenly in the frame.
2. If misaligned, adjust the mounting screws located on the sunroof motor assembly.
3. Tighten screws to the manufacturer’s specifications (usually around 6-8 ft-lbs).
4. Test the sunroof function again to ensure it operates smoothly.
