Ensure the vehicle is parked on a level surface.

2. Inspect and Repair Door Seals

Step 2: If damage is found, carefully peel back the old seal using a trim removal tool.
Step 3: Clean the surface of the door frame with rubbing alcohol.
Step 4: Apply the new seal, ensuring it is seated properly, and press firmly along the edges.

3. Clear Sunroof Drainage

Step 1: Open the sunroof fully.
Step 2: Locate the drainage tubes typically found in the corners of the sunroof frame.

Step 4: Test the drainage by pouring water into the sunroof channel and observing if it drains outside the vehicle.

4. Address Windshield and Rear Window Seals

Step 1: Inspect the perimeter of the windshield and rear window for cracks or gaps.
Step 2: If gaps are found, apply silicone sealant to the affected areas, smoothing it out for an even finish.
Step 3: Allow the sealant to cure as per manufacturer instructions before exposing to water.
