I have all the receipts of them having replaced the servo and the whole thumbdial/button console in the car. I think they might have also replaced the guts behind the glove box. After doing all this, they said it worked for about a month or two before something gave out. Could have been a vacuum leak or who knows. I bought the car around then, and when I drove it away only the hot defrost worked, which was fine with me as I describe above.

I thought about the Unwired tools thing, but you are still victim to the vacuum system and I just don't need the full features of the system enough to spend the $700. No, simple is beautiful, and reliable, and easy to fix.
