Oh, just cleaned this up, (sandpaper on glass), and measured a 7/16 ID in the heater output. (that, and the OEM stat go in in about a month).
Blend door is pretty self explanatory like you said! Yea it's lever is moving all the way to a stop. Actually a drain tube I think.
Actually it's usually hot enough for me, just doesn't kick ****.
I wonder if I can cut a hole right where a mouse nest might be!
