HVAC codes and strange issues
I've starting getting a ton of codes from my HVAC...mainly the ones dealing with the actuators and the outside/inside temp sensor. Codes are B0332/0337/0361/0365/0441/0446. I try to clear the codes in the DTC, but as soon as I clear them, 4 immediately pop back up. I then tried disconnecting the battery, and now I'm still getting the codes, and the HVAC display and all HVAC buttons are flashing on and off. It sounds like I'll have to deal with the actuators, and possibly the outside temp sensor (it was stuck on 69 degrees for about a week now), but does anyone have any suggestions on the flashing display and lights on the HVAC?

I'd start by checking the wiring to HAVC... When I benchtest a HVAC after installing LEDs, it reads 69 degrees. So you have zero connectivity with your temp sensor, flashing display and lights also seem to indicate an intermittnat connectivity problem.
Did you or someone else have the HVAC out to do any other work in the interior?

Finally got to pull everything out and take a look today, and no luck...the connector was still plugged firmly in the back of the HVAC control unit. I took the HVAC apart to see if there was anything obvious going on inside, but couldn't see anything. Tried disconnecting battery again, and also pulling the fuse for the HVAC, but no luck. Still flashing lights....
Is the controller a goner or is there something else I should be checking before I look for a new one?
