Ok, the 9460 is a fault code for the electronic blower regulator. If the blower is working fine the code can be ignored. The 9470 is a fault code for the heater booster. If the code continues to reset you may need to replace the booster. It is not a small task. The heater booster is located inside the heater housing behind the dash. If you have no complaints with the heating you do necessarily need to repair this code either. Let me know if you have any questions.
