My AC works fine, blows from the front panel and gets cold. Heat on the other hand is an issue. No matter what setting (floor, floor/def, def, front panel) no heat blows as it should. The cab gets warm as the heat does come on, but it does not come through the vents. I am hoping someone can point me in the right direction before I take it to be looked at.

Thanks.
