no you don't need a heater core, you need to have the heater controls checked as it sounds like the heat doors are open all the time and they should close when the control is turned off.

There is a "blend door" inside the heater box that allows air to enter either through the heater core, or the A/C element.
It's stuck in the "heat" position.
Either a cable came off, or the rotator servo is bad depending on the year of your truck.

Your gonna need to be a bit more specific as to what is happening. Unless your heater core is leaking it has nothing to do with the problem from what little information you provided. I would assume that your problem is more a blend door problem or heater control valve.

No you don't need a heater core.Check for a air leak .Sounds like there is no air getting to your heater controls.Sometimes the air leak is on the back side of the motor.
