Where is the valve block located at Benzmac? According to the Cd it looks as thought the suspected faulty actuator is behind the climate control. I will need to pull the dash to get to it though. Seems like a lengthy process (pull instrument cluster,etc.). Started on it yesterday, wanted to finish today but it is raining. Unfortunately, my better half has the garage filled with her "crap" and I don't have room to work on it in there. Guess I will have to wait for another day.
By the way, how was your vacation, Benzmac?
