Hi all - '99 XC70 in South Dakota, was working OK, though now switching the dial from Auto to Defrost (or any combination along the dial, high/low, etc.) does nothing. Air comes out, but only through main vents (not defrost). Is it just the dial? Seems like it has been slowly failing over time, and now don't hear that (customary) noise when some vents open and close with the changing of the dial. I am, apparently, a heavy breather because now it fogs up in no time! Not crazy about driving around with the windows halfway down.

Maybe related, maybe unrelated, but the fan switch stopped working awhile back as well. Put in a work-around that triggers the fan, but now it is on full blast or nothing, using a toggle switch that is not exactly original equipment. Thanks for any suggestions.
