Solution

1. Preparation

Gather tools and safety gear.
Disconnect the vehicle battery to ensure safety while working.
Tools Required: Screwdriver set, gloves, safety goggles.

2. Remove Cabin Air Filter

Locate the cabin air filter housing, usually behind the glove box.
Remove screws or clips holding the glove box in place.
Gently pull out the glove box to access the filter.
Remove the old cabin air filter. Discard it properly.

3. Clean HVAC System

Use a disinfectant spray or HVAC cleaning solution.
Spray the solution into the intake vents while the blower motor is running to ensure it circulates through the system.
Allow it to sit for the recommended time on the product label.

4. Check and Clear Condensate Drain

Locate the condensate drain tube under the vehicle.
Ensure it is not blocked by debris.
If blocked, clear the obstruction using compressed air or a small flexible brush.
