Why is my air conditioning not blowing cold air?
Present-day vehicles are designed to contain A/C refrigerant with very low leakage rates. Depending on environmental stresses, usage profile, and other factors, the refrigerant gas in the system may gradually deplete so that a "recharge" may be needed as the system ages.
The service department of your local Ford Dealership can both diagnose and check for leaks in your vehicle's A/C system. If any leaks or other service issues are detected, the system will be evacuated and the refrigerant properly contained. After servicing, the system will be refilled with refrigerant.
