I would suspect the thermostat is stuck in the open position so the water ( and motor ) never reach operating temperature. This is common where hard water ( water with a lot of minerals ) is in people's taps. I would suggest replacing the thermostat and draining out the coolant and replacing it with new antifreeze mixed with distilled water.
You could have an inoperative blend air door inside the dash, or the heater core is restricted internally.
This fluid can leak from many places. Look in places where water hoses meet the engine, where the heater hoses go into the firewall, the radiator and your heater core.
There are hoses in the engine compartment that go to the heater core. You can remove the intake and out going hoses from the heater core. You have to either block off these hoses or connect them together, depending on the make of the vehicle.

There are two hoses going to the heater core. Passenger side of the firewall in the engine compartment. Two 3/4 inch hoses about 3 inches apart.
windshield leaking heater core or heater core hoses.
Simply disconnect the heater hoses going to and from the heater, (Inlet & Outlet) at the firewall. Purchase the proper size hose coupling that will allow you to connect the 2 hoses together. Do not plug these hoses, just connect them together. The coolant will now not flow through the heater core.
Heater core is located under the dash and is held in with i believe 4 bolts which means the bottom half of dash needs to be removed but first you need to pop the hood and disconnect the inner and outter hoses going to and coming from the heater core at the wirewall, be ready cause some Coolant will come from the hoses.
hese hoses are called "heater hoses" they are from the front heater hoses which heat the car and they are connected to the front heater hoses under the car hood on right side
Simple, take the inlet and outlet hoses going to and from the heater core and connect them together.
