Why is my Air Conditioning leaking?
The Air Conditioning (A/C) system in your vehicle functions to both cool and dehumidify the air. Water vapor in the air blown through the A/C system condenses on the evaporator (located in the HVAC case behind the dash). This condensate normally drains onto the ground through a tube extending under the vehicle from the HVAC case.
After running the A/C, you may find a small puddle of water under your vehicle (usually under the front passenger footwell area). This is normal.
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, or accumulate as mist on the windows. If so, take your vehicle to your Lincoln Dealer for service.
