Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery for safety.
Ensure the vehicle is parked on a level surface.

2. Inspect and Clear Sunroof Drains

Locate the sunroof drain openings (usually found at the corners of the sunroof).
Use compressed air or a flexible wire to clear any blockages.
Pour a small amount of water into the sunroof channel to ensure proper drainage.

3. Check Door Seals

Inspect the rubber weather stripping around the passenger door for cracks or detachment.
Replace any damaged weather stripping.
Run a water test by pouring water over the door to check for leaks inside.

4. Examine Windshield Seal

Inspect the windshield for gaps or signs of leakage.
If the seal is compromised, remove any trim molding carefully.
Re-apply adhesive sealant to the edges of the windshield where needed.

5. Inspect Cabin Air Filter Housing

Remove the cabin air filter cover.
Check for signs of water intrusion or debris.
Clean out any debris and replace the cabin air filter if necessary.

6. Test HVAC System

Turn on the HVAC system and set it to the defrost mode.
Check for excessive condensation on the passenger side.
Ensure that the AC drain is not blocked, allowing condensation to drain properly.
