my Volvo XC60 has a bad odor coming from the AC, how do I fix it?

Solution

1. Preparation

• Gather tools and materials:
  • Screwdrivers
  • Cabin air filter replacement
  • AC cleaning spray
  • Safety goggles and gloves
• Ensure the vehicle is parked on a level surface and the engine is off.

2. Replace Cabin Air Filter

1. Open the glove compartment and remove its contents.
2. Locate the cabin air filter cover (usually behind the glove compartment).
3. Remove the cover by unscrewing or unclipping it.
4. Take out the old cabin air filter and inspect it for dirt.
5. Install the new cabin air filter in the correct orientation (check airflow direction).
6. Reattach the cover and close the glove compartment.

3. Clean the AC Evaporator

1. Access the AC evaporator unit; this may require removing the dashboard or other components.
2. Spray the AC cleaning solution onto the evaporator coil and surrounding areas.
3. Allow the cleaning solution to sit for the recommended duration (refer to product instructions).
4. Wipe down any accessible surfaces around the evaporator with a clean cloth.
5. Ensure the evaporator drain is clear of obstructions.

4. Final Assembly and Testing

1. Reassemble any components removed to access the AC system.
2. Start the vehicle and turn on the AC to the highest setting.
3. Monitor for any remaining odors and ensure airflow is restored.
4. If odor persists, consider repeating the cleaning process or consulting a professional.
