Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and ensure it is turned off.
Disconnect the battery if working with electrical components.

2. Inspect and Replace Door Seals

Carefully remove the damaged door seal using a trim removal tool.
Clean the area where the seal was attached to remove any adhesive residue.
Install the new door seal by aligning it properly and pressing it into place.
Ensure the seal is seated correctly and check for any gaps.

3. Clear Sunroof Drains

Locate the sunroof drain openings, typically found at the corners of the sunroof frame.
Use a flexible wire or compressed air to clear any debris blocking the drains.
Pour a small amount of water into the sunroof channel to ensure it flows freely through the drains.

4. Reseal Windows

Inspect the windshield and rear window for any signs of leakage or poor sealing.
If leaks are identified, remove any old sealant using a scraper.
Apply a new bead of automotive sealant around the edges of the windshield or rear window.
Press the window firmly into place and allow the sealant to cure as per manufacturer's instructions.

5. Weather Stripping Inspection

Check the trunk weather stripping for wear or damage.
Remove the old weather stripping and clean the surface.
Install new weather stripping by pressing it firmly into the designated channel.
