No matter where I set the controls at MAX AC, NORM , VENT or DEFROST about 20 % of the air is always blowing at my feet. I replaced out the plastic blower cage with the metal one as others stated this helped the air flow amount and then realized this was not the issue. Found a couple old posts that talked about the issue but was wondering if anyone had some pics or detailed instructions on how to fix this. AC isn't as effective when it bowing on your feet.
