HVAC codes
I installed a new old stock dual climate control I bought from a private party that originally bought it when he owned a C5, but after selling the car and never having installed it, did not need it any more, Its been in about 6 weeks. At what might be the same time, I started to have some issues...a bummer for a new unit. I am getting a groaning sound from the right side baffle acuator, sort of a quiet but hearable "Ogg-Ahh-Ogg-Ahh-Ogg-Ahh" that just goes on and on. I retreived the HVAC codes which are ....
B0365 Right Actuator Feedback Short to GND
B0446 Right Actuator Out of Range
This seemed to start up co-incidently with the new head being istalled....Anyone have any ideas if this might be a faulty control head, or is likely just coincidence that an acuator or its wiring has failed at the about the same time?
Definitieve answer would be to put in one of my old HVAC heads, but the other ones all have burned out bulbs and bad resistors that operate the display...and they need to be rebult. I hate to go through all the trouble to put back in head with bad light bulbs and display if I don't have to....
Any thoughts?!

Thanks...I'm going to try that this afternoon.....I also found a note from some years ago about killing power to the head unit by pulling the fuse, to force a re-boot of whatever is "confused" in them.... Lets hope that either a RESET or a power cycle will do the job...

No luck clearing codes....they come up in the report as both H for history and C for current....so reset only removes the H for a few moments, ..then it comes back. Pulling fuse, then re-power and also doing the fill system RESET makes no changes in the problem. I think I have to re-install one of the other control heads to see of the problem persists, in which case I have probably do have a bad acuator, or a jammed flap-door.
