Solution

1. Preparation

Gather tools: screwdriver, vacuum cleaner, and replacement parts if necessary.
Ensure the vehicle is parked in a dry area and turn off the HVAC system.

2. Inspect and Replace Cabin Air Filter

Open the glove compartment and remove the contents.
Locate the cabin air filter access panel and remove it using a screwdriver.
Take out the old cabin air filter, checking for dirt and debris.
Clean the filter housing with a vacuum cleaner.
Install a new cabin air filter, ensuring it is oriented correctly.
Reattach the access panel and close the glove compartment.

3. Check and Repair HVAC System

Turn on the vehicle and set the HVAC system to fresh air mode.
Activate the air conditioning and observe for any unusual noises or lack of airflow.
If airflow is obstructed, check for blockages in the vents or ducting.
If the air conditioning is not functioning, consider recharging the refrigerant or replacing the compressor.

4. Inspect Seals and Windows

Examine door seals and window seals for signs of wear or damage.
Use a flashlight to check for gaps or areas where moisture could enter.
If seals are damaged, replace them with OEM parts to ensure a proper fit.
