Are both your lines getting warm? If both hoses are warm/hot but you're still only getting mediocre then I wonder if your blend doors aren't working correctly.
I'd guess it could be the heater core but if both hoses are warm/hot then the heater core should be warm/hot too.
Yes, both lines were very hot. I think I need to look at the HEVAC diagrams and sort out what would be affected by the blend door that I broke (and fixed). NO air is coming out the four main vents, only out the defrost and floor vents, so something is wrong.
