Solution

1. Preparation

Gather tools and safety gear.
Disconnect the vehicle battery to prevent electrical issues during repairs.
Ensure the vehicle is parked on a level surface.

2. Inspect and Replace Door Seals

Tools Required: Trim removal tool, adhesive.
Check all door seals for cracks or detachment.
If damaged, remove the old seal using a trim removal tool.
Clean the surface where the seal attaches and apply new adhesive.
Press the new seal into place and allow it to set according to the adhesive instructions.

3. Clear Sunroof Drainage Tubes

Tools Required: Compressed air or a flexible wire.
Access the sunroof drainage tubes (usually located in the corners of the sunroof frame).
Use compressed air to blow out any blockages or use a flexible wire to clear debris.
Test the drains by pouring water into the sunroof area and ensuring it flows freely out of the underbody drains.

4. Reseal Windshield and Rear Window

Tools Required: Caulking gun, windshield sealant.
Inspect the windshield and rear window for any gaps in the sealant.
Apply new sealant where necessary, ensuring a tight seal around the edges.
Allow the sealant to cure properly as per manufacturer's instructions.

5. Repair Floor Pans and Body

Tools Required: Grinder, body filler, paint, and rust treatment.
Inspect for any holes or rust in the floor pans or body.
Grind out rust and apply rust treatment.
Fill holes with body filler, sand, and repaint to prevent further rusting.

6. Clear A/C Drain Tube

Tools Required: Compressed air or a long flexible tool.
Locate the A/C drain tube, usually found underneath the vehicle.
Ensure it is not blocked by debris.
Clear any blockage with compressed air or a flexible tool.
