either the heater core is clogged or the blend door is not functioning.
the heater hoses should have about a 30 degree difference in temp.

move the heater switch from hot to cold listen for a change in the air flow. if you don't hear any change. you may have a vaccum leak, damper door or motor not working. that won't let heat from the heater core be blown into the cars vents.
