Air condition whining noise
So I'm trying to figure out if this is normal because when I first bought the car I never noticed it. Whenever I run the air vents on high coming from the vents there is a high pitch sound coming from the passenger side. It gets louder the higher I turn the air up and since I've started noticing it my air seems like it is weaker. Air comes out of all 4 vents and the sound doesn't happen on defrost only on vents and foot vents. Anyone have any ideas?
