idahombz, I had this same issue where I had to turn the dial further and further to get the clicking to quit until it stop working all together. It is the air blend motor and can be fixed for free if need be. Here's what I posted:
Had put this off for awhile because it was winter for one, and because the first time I took out the glove compartment to take a look for some reason I just wasn't seeing the air blend motor. So, today (getting hotter here in Vegas), I decided to take another look. To others...after you remove the glove box only which is just a few...4...I believe screws and disconnect the glove box light, just slide it out. If you reach in on the left top side and pull down the cloth backing just enough to see inside you will see a white plastic lever mechanism. Now for the really good part.....I now have ice cold air and didn't spend one penny, mess with an air bag, take off any part of the dash, radio etc., I simply turned the climate dial...which did absolutely nothing.....except!....allow me to manually move the white plastic lever to the opposite position thus switching me from hot air to ice cold air. I will probably replace the air blend motor at some future time but for the summer I have cold air and if need I can take the glove box out at winter and switch to hot air...and although I haven't tried it yet there is a small possibility that I may be able to remove the air blend motor without doing anything more than I've already done (small hands...and don't you believe the rest of that myth). Now on to my new issue which I believe to be the torsion bar bushing clicking issue.
Some may say this is temporary but when it gets cold enough to need heat I will just quickly remove the glove box and move the position of the air blend motor to the heat position.
