Flap Positions Clarified

Steve, thanks for the comments and part numbers. My wife just got back so I was able to take another look. It seems that in defrost, the center vent is open and the fan goes to high speed. In normal operation, it appears that the defrost vents are still open and I think the whole system is stuck in recirc.

What is the best way for a DIY to check for vacuum leaks on the valves?

tks again for all your help.
