Re: Help with air vents please.
It sounds like the vent next to the radio might have slipped. The face of the dash around the radio basically snaps in and out (our techs drive Ford vans, we used to pop them out all the time to add our own devices), but I can't remember if you have to pop the radio, first. If you do, slide an allen key in far enough so that you push back the clips that hold it in (there's a tool for this, but allens or any thin rod will do), and the radio will come right out. If you're not brave enough to pop the dash without further proof, turn the AC on full blast and feel the dash around the radio. If it starts to feel really cool, you're most likely leaking there. Odds are, you're going to have to pull the dash, anyway.
