Make sure your AC rad is clear of obstructions, like dirt or bugs. Blow it out with compressed air or a pressure washer. Be careful not to bend the fins. That's another thing, if you have a lot of fins that are bent over, it won't get enough air through either.

Air conditioning

You need the AC mode/function switch to be replaced, it controls the different modes the AC/Heater are set to and where the air goes within the air ducts..
