My air conditioning is blowing hot so my brother says I need some Freon. He put Freon in my car while the air conditioner was on and the air didn't get cool at all. My brother told me he noticed that when the Freon was coming out of the can, it didn't get cold. Also, he notice that when I turned on my AC, it didn't "click" to turn on one of the AC components (I guess). I don't know if this mean anything, but I notice a black plastic webbing (Like off a filter) in the heating/cooling exhaust vents.
