Is the sound coming from the blower motor? The bearing in it may have gone bad.

Hi:
My guess is that the blower motor is bad. This may sound crazy, but when it's making the noise, put your ear under the dash on the passanger side. Let me know if that is where the sound is coming from.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
