Before you remounted the blend door actuator, you should switch the temp selector to "hot" if the door was in the hot position. If the blend door was in the cold position then the switch should be in the cold position before reinstalling the actuator. You may have to manually move the actuator gear to get it lined up.
The "stops" for the blend door actuator movement are computer controlled. And if the actual door and the actuator are not lined up correctly a dealer will have to calibrate them via the computers, or they will not work correctly. They may even break something if not installed right.

Yep, that's what I did. Seems to be fine. Now. I still got no heat on the drivers side floor, but plenty of air movement. I was looking on the KA forums and it looks like it might just be the way the air is channeled to the floor vents.
As I side note, i tried reversing the floor thru the core yesterday and the heat issue was even worse, it was pretty much cold on the drivers side. Wish I could snake the dang thing
so I was looking at blend doors, actuators...you mame it, I just could not believe it was the heater core again...it was just replaced! 
Well the sensored word at the stealership didn't flush the system when they replaced the core! 
So after reading this thread, I did a core flush and it was clogged! And the heat works great again on both sides, Driver and Passenger! 
Glad we were able to help.
