It comes out of the side ones, the bottom ones, and the top ones under the windshield, but that is it. No clue what is wrong. I have checked and they are not blocked or anything of that sort.

Hello, I am Danny.

Sounds like you are having trouble with the Blend Door Actuator. It is located on the heater-A/C box under the dash. I have attached a picture of what it looks like and location (#11-Mode Door). I have also attached a tutorial showing what is involved for the replacement. Hope this helps and thanks for using 2Carpros.
