HEATING PROBLEM WITH 1994 ES300

I have a 1994 6 cylinder automatic Lexus ES300. I've recently discover a anti-freeze leak but not sure where it's coming from at this time.
My problem is the inside heating which becomes cool air after increasing the fan speed. When the fan is idle, I feel heat coming out of the vents while the car is in motion. I've checked to make sure the AC isn't on and the car engine isn't over heating. Any ideas as to what the problem may be in this case?

Are you having fog appearing on your car windshield when heater on defrost? If so the heater core is bad. Turn car on and check for where the leak is comign from, check every hose for cracks or cuts and see if they are tightened properly.
