Air Vents not blowing???
I have a 05 6.0 and my air vents just stopped working. The only one it is blowing out of is the Defrost. I have the electronic control module in the truck, i've had trouble with this unit in the past but i changed a fuse an haven't had any troubles like this before. When i push the buttons on the module to switch to blow air on feet or face, i can hear it act like its working but the air doesn't change off of defrost mode. My other problem was the unit just wasn't working but it's fine now. Any ideas, thanks guys
