Ensure the vehicle is parked on a level surface and the interior is dry.
Disconnect the battery if any electrical components will be removed.

Tools Required: Flathead screwdriver, replacement door seals.
Carefully remove the old door seals using a flathead screwdriver.
Clean the area where the seals were seated to ensure proper adhesion.
Install new door seals by pressing them firmly into place, ensuring they fit snugly.

3. Clear Sunroof Drains (If Applicable)

Tools Required: Compressed air or a flexible wire.
Access the sunroof drain tubes, typically located at the corners of the sunroof frame.
Use compressed air or a flexible wire to clear any blockages in the drain tubes.
Test the drainage by pouring a small amount of water into the sunroof area and ensuring it drains properly.

4. Reseal Windshield/Rear Window

Tools Required: Windshield sealant, utility knife, scraper.
Carefully inspect the seals around the windshield and rear window for any gaps or deterioration.
Use a utility knife to remove any old sealant.
Apply new windshield sealant evenly around the edges.
Allow the sealant to cure according to the manufacturer's instructions before using the vehicle.
