I've replaced everything possible in this car the heater will not throw hot air, it does blow cold air. The latest thing I replaced was the Climate Control Unit, the day we replaced it we had heat the next day no heat. Like I said it's blowing cold air only. Any suggestions?

We don’t know what is it that you replaced

lets start with the basics
heater hoses are they both hot or not
did you check blend door operation ?
