2004 S60 Damper Motor Problems

[Mrgraham]

When the car is first powered up the blower will be full blast in the front defrost mode. I can turn the blower down but it still blows hot air through the defrost ports below the front windshield. It gets very hot in the cabin, so I am thankful it is winter.
I had lunch with a client whom owns a repair shop and he put a scan tool on it and it generated the following codes: CCM-000C Right Temperature Damper Motor, Signal too low, CCM-000F Damper Motor, Defroster, Signal too low.
We decided to re-set the system using the scan tool and following the re-set procedures then the system generated the following codes: CCM-000C Right Temperature Damper Motor, Fault, CCM-000F Damper Motor, Defroster, Fault.
So I could surely throw parts at this and replace the Damper Motors, but am curious if anyone has dealt with this issue and can comment if changing the motors solved the issue, or if there is another component that should be checked.
