I've put in 2 different CCU's and I know it isn't that. I'm sure it's a vac issue. I had a very high pitched whistle from under the dash prior to this happening. It only whistled at idle and it was extremely loud. That has gone away and this problem has become less erratic and more consistent. I'm sure the whistle was a pin size hole in a diaphragm that has now gotten larger.

So, which direction of the fresh air/recirculate flap is recirculate? The flap all the way to the right closes that opening over the squirrel cage fan, but my pea brain can't tell which is fresh air and which is recirculate.
