Whistling heater on Pajero

Sounds funny ha? If I have it on cold or a/c it's fine, once I start to turn up the heat it starts to whistle very softly, and gets louder the higher the temperature is. It isn't too loud, just annoying and have to have the radio louder. Anyone had this? is it going to cost me loads of dough?
