Solution

1. Preparation

Gather tools: socket set, flathead screwdriver, vacuum, and a cleaning solution.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues while working on the HVAC system.

2. Remove the Cabin Air Filter

Locate the cabin air filter housing, usually found behind the glove compartment.
Use a flathead screwdriver to gently release the glove compartment’s retaining clips.
Remove the glove compartment to access the cabin air filter.
Take out the cabin air filter and inspect it for mold or rust. Replace if necessary.

3. Clean the HVAC System

Use a vacuum to remove any debris or dust from the air intake area.
Mix a cleaning solution (such as a mild disinfectant) with water and spray it into the air intake ducts.
Run the HVAC system on high for 10-15 minutes to circulate the cleaning solution through the system.

4. Inspect and Clear Drain Hoses

Locate the drain hoses beneath the vehicle, typically near the firewall.
Check for blockages or kinks in the hoses that could prevent proper drainage.
Clear any obstructions to ensure moisture can drain away from the vehicle.

5. Reassemble and Test

Reinstall the cabin air filter and glove compartment.
Reconnect the battery.
Start the vehicle and run the HVAC system to check for any residual smells and ensure proper airflow.
