Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical issues during repair.
Allow the vehicle to cool if it has been recently used.

2. Inspect and Clean the Seals

Remove any debris around the sunroof seals.
Use a soft cloth and mild cleaner to wipe the seal surfaces.
Check for any cracks or deformities in the rubber seals.

3. Clear the Drainage System

Locate the sunroof drainage tubes (typically found at the corners of the sunroof).
Use a compressed air canister or a flexible wire to gently clear any blockages.
Pour a small amount of water into the sunroof channel to ensure it drains properly from the tubes.

4. Replace Damaged Seals (if necessary)

If the seals are damaged, remove the old seals by gently prying them off.
Clean the area thoroughly before applying new sealant.
Install new seals, ensuring they sit flush against the sunroof frame.
Apply adhesive if required, following the manufacturer's instructions.

5. Re-test Sunroof Operation

Reconnect the vehicle battery.
Open and close the sunroof several times to ensure proper operation and alignment.
Check for any leaks by conducting a water test (pour water around the sunroof).
