First, check the lines going to the heater core. Make sure they're both very hot (after fully warmed up, obviously). You can also reach up and feel the plenum under the passenger side kick panel. If it's warm, your blend door is probably stuck. If the lines and/or the plenum is cold, the heater core is clogged. Have you taken care of your coolant (clean/full)?? Heater cores usually fail by leaking in the cab and steaming up the windshield.
