Solution

1. Preparation

Tools Required: Flashlight, water source (hose or bucket), towels for drying, vacuum for water removal.
Ensure the vehicle is parked on a level surface and the interior is dry before beginning repairs.

2. Seal Inspection and Replacement

Inspect Seals:
- Carefully examine all door and window seals for tears, cracks, or any signs of deterioration.
Remove Damaged Seals:
- Use a trim removal tool to carefully detach any damaged weather stripping or seals. Work slowly to avoid damaging the surrounding areas.
Clean Surface:
- Clean the area where the seal will be applied using a mild solvent and cloth to remove any residue.
Install New Seals:
- Apply the new weather stripping or seal in the correct orientation, ensuring complete contact.
- Use a roller tool to press down firmly along the entire length for optimal adhesion.
Recheck Drainage:
- Ensure that drainage channels are clear and functioning correctly by pouring water through them and observing flow.

3. Address Drainage Issues

Locate Drain Tubes:
- Identify the drainage tubes from the sunroof and windshield cowl.
Clear Blockages:
- Use compressed air or a flexible rod to clear any blockages in the drainage tubes.
Test Drainage:
- Pour a small amount of water in the sunroof area to ensure it drains properly without any leaks into the cabin.
