If it is the heater, You need to replace the heater motor. There are some upgrades that you can do if this is the case. If it's the fan belt it's because it's drawing power from the alternator and you may have to replace the belt. Check the idler like lefthand said and also check all pulleys in the system for play.

Here is what is sounds like. The squeal is not coming from the engine, it's coming from the inside Heater, so it maybe the heater motor. I'm going to check both out thanks

Yup. That's coming from the heater.
