Ok, thank you for replying again. I was under the impression that a tear in the monovalve would have meant heat all of the time rather than what you described with heat only when you start the car on the max heat setting and not changing the dial at all. I drove the car around and did some tests and what you described is what is happening to me. I'll definitely pull that thing out and see if I can notice any breaks or problems with it. BTW, I don't play around with the climate control dial when its working properly, I just start playing around with it when something isn't working and I'm trying to see what exactly the symptoms are. Hopefully thats the only problem with the CC, and now I will just have to fix the rough idle until she's warmed up!
