2001 Jeep Grand Cherokee Laredo I6

I had AMCO replace my AC/Condenser with the
Upper Hose, then Dealer replace my Heater Core
and Evaporator along with an Actuator for the
Blend Door. My AC gets down to 50-60 Degrees
and mostly blows out the Center Driver Vent on the
dash, and the Defrost vent for the windshield
blows hard, air seeps through the other vents very
lightly on the passenger  side dash, The Floor
blows lightly as well.

Some say the Blend doors are broken, but the
dealer did not find any broken when they replaced
the Core and Evaporator.

[I read the Fan could be blowing in the wrong
direction]
I’m a few thousand into this already, anyone with
first hand experience can point me in the right
direction before I blow away more money would be
greatly appreciated.
