Why is there an odor coming from the Air Conditioning vents?
In Air Conditioning (A/C) mode, air blown across the evaporator is cooled, and moisture in the air condenses on the evaporator. Dust, pollen, and other contaminants can mix with this condensate, supporting the growth of microorganisms. In warm, damp conditions, bacteria and fungi may build up on the evaporator. These microorganisms may cause some odors. If you use your vehicle's A/C system only for short periods, then it may be especially prone to this phenomenon.
To reduce the chance of such a buildup in your vehicle's A/C system, follow the recommendations below:
- Where feasible, run the A/C system for longer periods.
- When more condensation collects and drains off the evaporator, it has a cleaning effect on the evaporator. Contaminants are washed off the evaporator by condensate and drain out of the HVAC case to the ground below the vehicle.
- If your vehicle has a cabin air filter, replace it when it gets dirty.
- The service department at your Lincoln Retailer can apply an aerosol disinfectant to destroy the odor source. For some driving conditions, it may be necessary to repeat this treatment several times.
