Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Repair Door Seals

Sub-steps:
1. Use a flashlight to closely examine the rubber door seals for cracks, tears, or compression.
2. If damaged, replace the seals with OEM parts. Remove the old seal by gently pulling it away from the door frame.

Sub-steps:
1. Inspect the windshield for gaps or cracks.
2. If there are issues, consult a professional for windshield replacement or resealing.
3. For minor gaps, apply a clear silicone sealant around the edges to prevent water ingress.

5. Check HVAC Drainage

Sub-steps:
1. Locate the HVAC drain tube under the vehicle.
2. Ensure the drain is not clogged by inserting a small wire or using compressed air.
3. If blocked, clear the obstruction and check for any signs of leaks in the HVAC system.

6. Inspect and Repair Trunk Seals

Sub-steps:
