1. Preparation

Gather necessary tools and parts.
Disconnect the battery for safety if working on electrical components.
Ensure the vehicle is parked on a level surface.

2. Inspect and Replace Door Seals

Remove any trim panels around the doors if necessary.
Carefully peel back the old weather stripping.
Clean the door frame area with isopropyl alcohol to ensure proper adhesion.
Install new door seals, ensuring they fit snugly without gaps.
Reattach any trim panels removed during the process.

3. Repair Windshield Seal

Inspect the windshield for visible gaps or damage.
If gaps are found, carefully remove the old seal using a trim removal tool.
Clean the windshield and frame area thoroughly.
Apply new automotive-grade sealant or adhesive along the windshield frame.
Press the windshield into place and secure it, following the manufacturer’s curing time instructions.

4. Clear Sunroof Drains

Open the sunroof fully to access the drainage points.
Use compressed air or a flexible wire to clear any debris from the drain tubes.
Test the drains by pouring a small amount of water into the sunroof channel and ensuring it drains properly.

5. Check and Replace Bed Rail Seals
