Ac problems and codes please help
Hey guys, my ac hasn't been working and its super hot where I'm at. The heat works on my top(defroster) vents,feet vents, and the rear vents but not in the center vents. Tried adjusting everything on idrive, replaced the blower motor and resistor already. Whats next, heater valve control? Please, help! I've spent 500 on parts and diagnosis already and no one seems to be able to pin point the problem. I also added the codes my car is throwing off on the bottom, can you let me know which parts I need to replace. Any insight would be greatly appreciated. Help a brotha out, this thing is sucking me dry.

what parts did you replace, all of those sensors? are you sure your IHKA isn't bad?? they do fail from time to time, I used to replace them in E36s, E39s, and E38s at my shop fairly regularly.
