| INTERMITTENT LACK OF A/C – AFTER EXTENDED DRIVING AND HOT HUMID CONDITIONS – EVAPORATOR CORE ICING |
:
2013-2014 Escape vehicles built on or before 7/22/2014, 2015 MKC vehicles built on or before 7/13/2014 and 2013-2015 C-MAX and may exhibit an intermittent lack of Air Conditioning (A/C) and/or a loss of airflow from the vents.
This may occur after extended operation in hot, humid conditions.
This is likely due to the evaporator core icing.
SERVICE PROCEDURE
- Evacuate and Recharge the A/C System.
- Make sure the same amount of oil recovered is returned to the A/C system.
- Replace the cabin air filter.
- Replace the evaporator temperature sensor.
