Heater problems

[IronMike]

Hi! Out of nowhere my heater stopped working. The fan blows no problem but all I get is cold air. I've tried various settings and putting it down to cold and back to hot but with no luck. Can anyone point me in any direction? Thanks in advance.....IronMike

PS) The anitfreeze looks okay, plenty in there and the cold/hot gauge is right in the middle where it always is.

Feel the heater hoses (with the truck off & hot) to see if the heater hoses are hot or cold. If the hot water is circulating threw the heater and out than it could be your heater blend door. If its not circulating than it could be a pluged heater core or something else in the heater.
