B1265 - Cold air bypass door actuator circuit failure.
B2798 - Driver coolant control valve circuit short to ground.
B2799 - Passenger coolant control valve open circuit.
Since you have heat all the time, the B2799 I feel is the problem. Here is a test:
1) Key in off position.
2) Disconnect coolant control valve.
3) Key in on position.
4) Measure the resistance between ground and coolant control valve plug.
5) Is the voltage greater than ten volts?
It sounds like you have a blend door actuator for the fresh air door and a coolant control valve that is out and needs to be replaced.
Here is a guide to help you see whats goes on when doing the repair:
Below are some diagrams to show you on your car.
Let me know.
