You probably have a blend door actuator problem. Can you control where the air comes out of the vents? There should also be a vacuum operated hot water valve in the engine bay. Check the operation of the hot water valve. The blend door actuator is located on the driver's side of the HVAC case behind the dash. Check to see if the linkage moves as you operate your heater control.
