How do I Check If the Air Conditioning System is Leaking?

Your vehicle’s air conditioning system is designed to both cool and dehumidify the air for your comfort. During this process, moisture from the air condenses within the system and is safely directed outside through a drain tube located beneath the vehicle.

Water vapor in the air blown through the A/C system condenses in the evaporator (located in the Heating Ventilating and Air Conditioning (HVAC) case behind the dash). This condensate normally drains onto the ground through a tube extending under the vehicle from the HVAC case.

It is perfectly normal to see a small puddle of water on the ground after the A/C has been running, typically appearing under the front passenger footwell area.

In some cases, the drain hole may become plugged or dislodged, and the condensate may leak into the vehicle interior, onto the carpet in the footwell area and/or accumulate as mist on the windows. If so, please take your vehicle to your local Ford Dealership to have the system inspected and serviced.
