Solution

1. Preparation

Gather tools and materials: flashlight, water source (garden hose), towels, silicone sealant or new seals as needed.
Ensure the vehicle is parked on a level surface and the interior is clear of personal items.

2. Inspect and Replace Door Seals

Sub-steps:

Sub-steps:
1. Inspect the windshield and rear window for any visible gaps in the sealant.
2. If gaps are found, use a razor blade to carefully remove any old sealant.
3. Clean the area with glass cleaner and let it dry.
