My 07 Mustang is leaking water inside the car under the dash on the passenger side what is causing this

EVAPORATOR (PART OF A/C) PAN IS FULL OF WATER BELOW IT

DRAIN SHOULD BE ON THE OTHER SIDE OF THE FIREWALL (UNDER THE HOOD)

MOST LIKELY IT IS STOPPED UP

NEED TO KNOW HOW TO UNSTOP IT?

THE MEDIC

IT IS ALSO POSSIBLE THAT THIS MAY BE COOLANT---DOES IT SMELL LIKE ANTI-FREEZE?

YOU MIGHT SOAK UP A LITTLE ON A WHITE KLEENEX---IS IT THE COLOR OF YOUR COOLANT?

IF SO THIS MAY BE A HEATER HOSE OR HEATER CORE LEAK

I'M BETTING ON THE A/C DRAIN

EVEN NOT USING A/C---DEFROST MODE ALSO MAKES IT COME ON---THIS TAKES MOISTURE OUT OF THE WARM AIR BEING BLOWN ON YOUR GLASS FOR BETTER DEFROSTING AND FASTER.

YOUR TURN
