So this squeal started around august and I cannot figure it out, it is aggravating to have to hear, I’m not sure of this is a result of the blower motor bearing wearing out, or if this is another problem I cannot figure out, please help, follow this link to listen to what it is doing, it also does it sometimes when the heat is on sometimes

Usually that is a sign of the blower motor wearing out. You may find that the squeal will go away temporarily running the blower at higher speed. (Your youtube video is marked private.)
If the sound changes pitch when you change the fan speed, then it's the blower motor.
