Solution

1. Preparation

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

2. Inspect and Replace Weather Seals

Tools Required: Screwdriver, trim removal tool
Inspect the weather seals around the doors and trunk. If damaged:
- Remove the old weather strips using a trim removal tool.
- Clean the area where the new seals will be applied.
- Apply adhesive (if necessary) and press new weather strips into place.

3. Clear Sunroof Drains

Tools Required: Flexible wire or a vacuum with hose attachment
Locate the sunroof drain outlets, typically at the corners of the sunroof.
Use a flexible wire to clear any debris blocking the drains.
Test the drains by pouring water into the sunroof channel and ensuring it flows freely out of the drain outlets.

4. Reseal Windshield and Rear Window

Tools Required: Windshield sealant or silicone sealant
Inspect the sealing around the windshield and rear window for gaps or deterioration.
Clean the area around the seal.
Apply a bead of windshield sealant or silicone around the perimeter of the windshield or rear window to ensure a watertight seal.

5. Repair Body Cracks

Tools Required: Body filler, sandpaper, primer, paint
Inspect the body for any cracks or holes that could allow water in.
Use body filler to repair small cracks. Sand smooth once dry.
Apply primer and paint to protect the area from moisture.
