How do I clean the air conditioning to remove bad odours?
Get the engine hot. Find somewhere off street to park. Open all the windows. Turn the heater to max. Turn the fan speed to 3 (not 4). Then stand outside with the engine idling. The heat should kill off the bacteria in the ventilation trunking.
