G37 X A blowing semi cold

My mech I trust cant figure it out. I just had him charge it to correct pressure and its holding no leaks. I just changed cabin filter (Thank God) I do suspect it may be condensor blocked but though my mech would have tried it. Have a local garage out for $$ wants $2200 replace the compressor and drier at 64K miles right! not happening . My mech adamantly disagrees.

Does it properly cycle through all the different cabin vents and blower motor speed scales properly from low to high? Does it feel like it's pushing the correct volume of air out of the vents?
Pay particular attention to the blend motor, I think you can actually SEE it by removing the glove box and cabin air filter housing and using a flashlight and inspection mirror to look up into the ductwork while you operate the blend door from hot to cold. It's possible the hinge or something on it is broken and it's not closing completely thus letting hot air into the ductwork.

Air blows very strong when cycling through different settings.
