I was trying to remember more ways into that system. if you pull out the glove box tray you can get at the upper duct where it blows at the glass if I remember right. its like 1 or 2 screws and you can lift it up enough to see if anything is stuck down in it. just becarful not to break anything. with the glove box out you should beable to see your mode door accuators move also.
