Noise coming from AC?

[Fletch627]

My far right air vent makes a strange..squeeking noise sometimes when using the heat/air..it isn't always constant, but when it starts, it wont stop..any ideas to whats causing it?

Check the vent?
Idk if this could be the problem but check the cabin filter.

Its the cheap plastic fan that gm used. Over time it warps and distorts until it contacts the inside of its housing.
I had the same problem on a 1991 explorer, replacing the fan fixed it.
