2002 Prius Air Mix Servo

I have a 2002 Prius that puts out only cold air or warm air...but nothing in between. I thought the air mix servo was the problem, so I ordered a new servo and installed it. But I found that the new servo behaved the same way the original servo did! It let in only cold air when the temperature was all the way down, but then when you moved the temperature dial three short clicks clockwise, the servo rotated all the way open to let in the engine air. There was no incremental turning of the servo to mix the air temps at all, and this is my problem...

I am looking for incremental temperature control from my Prius, but the new parts don't provide that. Am I missing something?
