A/C problem
question 1) was the a/c not functioning properly BEFORE going to that shop
question 2) what was/did that shop do to your car, the area they were working on
question 3) are you saying the a/c was working ok before the shop and not working ok after?
just as a side note, i believe there are actuators that move parts (like shades) inside the unit, thats where usually the problem is when air moves incorrectly or fails to move properly.
this is a blow-up of the a/c unit. i think (but not positive) that the shades are item #1. the actuator is item #8, there are 2 of them(i know it show 3 of them but parts list says 2 required). also #29 is an actuator.

i am not a a/c unit repair person, but from what i can tell...
the purple area is for the dash vent air controling (i assume its ok)
the brown circle area is the shades , you say your getting air where is supposed to go, just wrong temp , so i would venture to guess your shades are ok.
the green area is the passenger temp actuator so i assume its ok if your getting ok colling/heat on passenger side.
the red area would be driver side, so that might be the problem area.
again, i dont know, its just an educated guess
others with real repair knowledge can now chime in

But.......in your case, since this just "coincidentally" started after being at a shop, I suggest trying what is admittedly a "long shot". Disconnect the battery for 30 minutes then reconnect and try the system. And remember you'll have to re-index the windows after reconnecting the battery.
Like I said, a long shot but it's free and easy so might be worth the effort.
Let us know.
