1. Preparation

Gather necessary tools and parts.
Park the vehicle in a well-ventilated area.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect Seals

Tools Required: Screwdriver, flashlight
Remove any trim panels around doors and windows if needed to access seals.
Visually inspect the rubber seals for cracks or tears.
If damaged, replace with OEM seals. Make sure they fit snugly against the body.

3. Check Cabin Air Filter

Tools Required: None necessary for most models.
Locate the cabin air filter (usually behind the glove compartment).
Remove the filter and inspect it for dirt or blockage.
Replace with a new cabin air filter if necessary.

4. Inspect Windshield

Tools Required: None necessary.
Check for any cracks or gaps in the windshield seal.
If found, consult a professional for windshield resealing or replacement.

5. Clear Drainage System

Tools Required: Compressed air, small wire or pipe cleaner.
Locate sunroof drains (if applicable) and check for clogs.
Use compressed air or a wire to clear any blockages in the drainage tubes.

6. HVAC System Check

Tools Required: OBD-II scanner (optional for deeper diagnostics).
Turn on the HVAC system to full speed and check for airflow at vents.
If airflow is restricted, inspect the blower motor and ducting for blockages.
