    whistling noise from vents

    When i turn my AC on it starts to making a whistling noise. At first it came on occasionally and i could ignore it. Now it comes on every time my AC is switched on. It's pretty loud. Is this fixable?

    Probably the blower motor. Might as well replace it.

      Only the AC or any time the fan is on? If it's any time the fan is on then it's probably the blower.

          Then again, it could be a leaf or piece of paper in the vents. Stranger things have happened

            Lol, speaking about strange things. When i was swapping my dash, I found a pen jammed in my vents in my old dash haha. No idea how the PO managed to get a pen in there.

            Its only when the AC is on. If i set the AC on and keep the fan on 0 it makes the noise. When i turn the ac off and put the at 2 it doesnt make the noise. I was thinking it may be debri as well. Hopefully I'll take it apart tommorow after work.
