CHEVROLET TRUCK HEATER PROBLEM

1997 Chevrolet Truck

My truck starts up and runs without problems, but the heater only blows cold air. Unsure about the temp select, but the directional switch and fan speed works fine. Any advise would be appreciated.

Does the engine reach normal operating temp? Are the heater hoses, hot? Maybe a problem with blend door, under the dash?
