I tend to agree. I had intermittent heat in my 300D (was getting more and more intermittent, i.e. COLD). I installed a new monovalve insert, and it's now working again. Though, I am wondering if I have other ACC issues. I normally run with first button inboard on the right selected (righmost button being "off"). I let the blower speed auto-adjust. With the dial set for heat, and cold outdoor temps, I get some airflow out the floor vents, some out the the side vents, and very little (but detectable) air flow out the center vents. The airflow is not what I would consider high-volume (compared to other cars I've owned) even when the interior is below the set temperatire and the blower is running on the highest automatic speed. Overall question, does this sound normal? Temperature regulation does seem to work, though it does take some time for the interior to attain the set temperature. I'm not sure what any of the middle buttons do. Does not seem to make a lot of difference which one I select. The solid/outlined up and down arrows have no intuitive meaning to me. Defrost (the far left button) works fine. Allan -- 1983 300D 1966 230
