I know that kind of contrary, but thats the easiest way to put it. When i was driving from a restaurant today it started.

My heat was on when it started. While me heats on i hear a Loud Knocking/ Ticking type noise (same with defrost) not so much like a metal on metal, but close. Once the car warmed up it went away, but i can still hear a light ticking. Now is the something along the lines of Heater core??* if thats the name for it. Or what, because i am not sure if this is something to be cause for a concern?
