My in car heating produces air when turned on and all aspects work perfect however it does not produce hot air inside the vehicle when you turn up the temperature.

Feel the upper radiator hose after the engine has been running a while. It should be too hot to hold onto for very long. If it is not, suspect the thermostat. If it is, feel the heater hoses. They should be just as hot. If they are not, suspect the heater core is plugged or there's a water valve inline with one of those hoses that isn't opening up when heat is selected. If the heater hoses are hot, suspect a problem with the actuator or cable for the temperature door in the heater box.
