2005 Cadillac CTS Water leaking from heater

Where is the water leaking from? If you find it under your vehicle and it is not antifreeze - then it is just condensation and is intended to drain out there - it's just water from the air that your air conditioning system takes out. If you have it inside the vehicle and it's not antifreeze then the condensation drain from the Heater and A/C case is plugged. This is easy to fix - let me know. If it is just an occasional drip inside the vehicle near the accelarator then it is just condensation on the A/C lines and nothing to worry about.
