Trouble codes same for 03 as 02 and erasing them only erases the C designations?

I just bought a 03 z06 yesterday and when I filled up with gas the first time right after starting engine it stalled. When I restarted the engine light was on. I checked gas cap thinking that was the problem but it was tight (chevron gas).

I got the codes and 7 were there and all but 1 of had a C code in addition to the H.

P0171 H
P0174 H
P1637 H
C1293 H
C1294 H
B0361 H C (apparantly this C is what triggered the light)
B0441 H

According to info I found on 02 Z06's (it didnt say 03's) the B0361 code I found is a "Left Actuator Feedback Short to GND". When I was retrieving codes it said this code was labled as 99-HVAC. what exactly is a Left Actuator Feedback Short to GND item? Are the 02 codes different from the 03 codes maybe?

I cleared all the codes one by one and the light went off for about 30 miles and then came back on. When I re-checked codes all the H ones were still there and this same one again with the H C. Once codes are cleared do the H ones still remain in the system even though i cleared them initially? As I reset the codes it said all were cleared but I am thinking the History ones stay in the system forever for reference of past trouble.

Thanks.

Heating and Air Conditioning: Testing and Inspection B0361

DTC B0361

CIRCUIT DESCRIPTION
The following DTCs are for the left and right air temperature actuators:
- B0361 and B0363 are for the left air temperature actuator B0365 and B0367 are for the right air temperature actuator

The HVAC control module commands the air temperature actuators to move by controlling the voltage supplied on the control circuit. A signal voltage of 0 volts or a signal voltage of 5 volts rotates the air temperature actuator. A voltage of 2.5 volts stops the door. The HVAC control module determines the current position of the actuator by monitoring the voltage on the signal circuit. The feedback potentiometer is a function of the motor position. The HVAC control module controls the air temperature actuator door positions in order to maintain the selected air temperature.

CONDITIONS FOR RUNNING THE DTC
The ignition is turned ON.

CONDITIONS FOR SETTING THE DTC
The HVAC control module detects the signal circuit is less than 5 counts (0.09 V), for B0361 and B0365, or more than 250 counts (4.9 V), for B0363 and B0367.

ACTION TAKEN WHEN THE DTC SETS
A default value will be used for the sensor data by the HVAC control module in an attempt to maintain the air temperature selected by the driver. This default value will be displayed on the scan tool.

CONDITIONS FOR CLEARING THE DTC
- The DTC will become history if the HVAC control module no longer detects a failure.
- The history DTC will clear after 100 fault free ignition cycles.
- The DTC can be cleared with a scan tool.

PS
A disconnected or broken door may also set this DTC by allowing the air temperature actuator to travel to its internal stops, an overtravel condition.

Thank you very much!

We were fooling with the driver and passenger control knobs right then so maybe it tripped something, but it looks like its also a past problem according to the H codes.
