Carefully pry off the interior trim surrounding the windshield using a trim removal tool.
Use a socket set to remove any screws securing the trim.
Set the trim aside in a safe location to avoid damage.

Check the windshield seal for any debris, dirt, or damage.
Clean the area using a soft cloth and isopropyl alcohol to ensure proper adhesion for any sealant applied later.

4. Reseal the Windshield

Apply a high-quality automotive windshield sealant along the perimeter of the windshield where it meets the body of the vehicle.
Use a caulking gun for even application, ensuring no gaps remain.
Smooth the sealant with a finger or a sealant tool for a clean finish.
