Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery for safety.

2. Cabin Air Filter Replacement

Tools Required: Screwdriver, trim removal tool
Locate the cabin air filter access panel (usually under the dashboard).
Remove screws or clips to access the filter compartment.
Pull out the old cabin air filter and clean the compartment.
Insert the new filter, ensuring it is oriented correctly.
Reassemble the access panel.

3. Inspect and Replace Door and Window Seals

Tools Required: Utility knife, adhesive (if necessary)
Visually inspect all door and window seals for wear or damage.
If seals are damaged, carefully remove the old seals using a utility knife.
Clean the surface before applying new adhesive if needed.
Install new seals and ensure they are properly fitted.

4. Drainage System Cleaning

Tools Required: Compressed air, vacuum
Locate drainage points such as sunroof drains and windshield drain channels.
Use compressed air to clear any blockages in the drain tubes.
Vacuum any debris or water buildup to ensure proper drainage.

5. HVAC System Check

Tools Required: Multimeter (if electrical issues are suspected)
Start the engine and turn on the HVAC system to full heat and fan.
Check for proper airflow from vents and ensure there are no unusual noises.
If airflow is insufficient, inspect blower motor and connections.
