Most likely, you have a leak in your heater core. This is a unit behind the car's firewall that circulates water+coolant through it so that your car's cabin heats up quickly when you turn on the heat in the winter. If there's a leak in your heater core, the engine's cooling water will come into the cabin. You need your dealer/mechanic involved to fix it.
