Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery (if working on any electrical components).
Ensure the vehicle is parked in a well-ventilated area.

2. Inspect and Replace Cabin Air Filter

Tools Required: Screwdriver, replacement cabin air filter.
Remove the cabin air filter cover, typically located behind the glove compartment.
Take out the old filter and inspect for dirt and moisture.
Install the new cabin air filter, ensuring it is oriented correctly.
Reattach the filter cover securely.

3. Check and Repair Door Seals

Tools Required: Visual inspection tools, possibly a trim removal tool.
Inspect door seals for any cracks, tears, or improper fit.
If damaged, remove the old seals and clean the area.
Install new door seals, ensuring a tight fit to prevent moisture ingress.

4. Inspect and Repair HVAC System

Tools Required: Multimeter, A/C gauge set.
Start the engine and turn on the A/C system to the max setting.
Check for proper airflow from vents, especially towards the windshield.
If airflow is weak, inspect the blower motor and ductwork for obstructions.
Repair or replace any faulty components as needed.

5. Resolve Any Water Intrusion

Tools Required: Water leak detection dye, flashlight.
If wet areas are found, use water leak detection dye and apply to suspect areas.
Inspect for leaks as water enters the vehicle.
Seal any identified leaks with appropriate sealant or repair parts.
