What would cause the heater to NOT blow warm air. The vehicle (engine temp) heats up normal and does not over heat but all I get inside is cold air. The blower works just fine but like I said it only blows cold air on heater as wall as defrost. Any sugestions why?

Are the heater hoses hot? Might be a temp door under the dash that has a problem?
