What could be causing my heating issues?


I have a 98 S-10 P/U 2.2 RWD w/o A/C auto trans. I am having heating issues. Engine gets to operating temperature and I get some heat out of the floor vents and out of the defrost vents. I have cold air coming out of the dash vents at all times. When I turn the switch to dash vents it only comes out of the dash vents and it is cold air. Any ideas??? I had a guy tell me that the control head was bad and it was causing the mode to override the blend door. Is this possible??
