Ensure the vehicle is parked on a level surface.

2. Inspect and Replace Door Seals

Tools Required: Flathead screwdriver, adhesive sealant (if needed).
Remove the door trim using a flathead screwdriver to access the door seals.
Inspect the rubber seals for cracks or detachment.
If damaged, replace with OEM seals and apply adhesive sealant if necessary.
Reattach the door trim securely.

3. Repair Windshield Seal

Tools Required: Windshield sealant, utility knife.
Inspect the windshield seal for gaps or damage.
If gaps are found, carefully cut away the old sealant using a utility knife.
Apply new windshield sealant around the edges and smooth it out.
Allow the sealant to cure according to manufacturer instructions.

4. Clean Sunroof Drains

Tools Required: Compressed air or flexible cleaning tool.
Open the sunroof and locate the drainage holes at the corners.
Use compressed air to blow out any debris blocking the drains.
Test the drainage by pouring a small amount of water in the sunroof channel to ensure it flows freely.
