why does my Skoda Octavia's air conditioning smell bad

Solution

1. Preparation

• Tools Required: Screwdriver set, vacuum cleaner, disinfectant spray, gloves, and safety goggles.
• Ensure the vehicle is parked in a well-ventilated area.
• Disconnect the battery for safety before working on electrical components.

2. Replace Cabin Air Filter

1. Locate the cabin air filter, typically found behind the glove compartment.
2. Remove the screws or clips securing the glove compartment, then carefully detach it.
3. Remove the old cabin air filter and inspect the housing for mold or debris.
4. Install a new, high-quality cabin air filter, ensuring it is properly seated.
5. Reassemble the glove compartment and ensure all fasteners are securely tightened.

3. Clean Air Intake and Evaporator Core

1. Access the air intake vents and use a vacuum cleaner to remove any debris or dust.
2. Spray a disinfectant cleaner into the air intake to kill mold and bacteria.
3. If accessible, spray the evaporator core with a specialized AC cleaner to remove any mildew.
4. Allow the system to run with the AC on high for about 10-15 minutes to circulate the cleaner.

4. Check and Repair Drainage System

1. Locate the AC drainage tube, usually found under the vehicle near the firewall.
2. Inspect for any blockages or clogs; clear them if necessary.
3. Ensure the drainage hose is properly connected and free of kinks.
4. Test the drainage by pouring a small amount of water into the system and ensuring it flows out freely.
