It’s possible one of the flaps inside is obstructed. Inspection with
A cheap borescope down the vents is about the only way to see.

@Stuey81 , did you get the issue resolved? I have exactly the same issue where all actuators work fine in the relearn mode, but it keeps throwing DTC#B0253 which indicates the actuator on the drivers side needs to be replaced. I purchased a new actuator and plugged it in and it does exactly the same thing as the original one.
yeah I did mate. At my wits end I took it to holden for diagnoses, turns out all the actuators were fine, and it was a rod that goes inside the hvac centre stack that had come off. You couldn’t see it and I never would have found it. All the linkages were attached as far as I could see, but it was actually inside the unit somewhere. I paid 2 hours labour and when I came back it was fixed, they even topped up the oil in the AC compressor, and threw new gas in it for me for no extra charge. Everything has been 100% fine since, and I use the car everyday.

Thanks Mate,

Gives me some more options to explore, other than that it's going to have to go to Holden.

VE S2 SV6
I am having HVAC issues with 2012 VE S2 SV6.

Randomly when I turn the car on the aircon will get stuck blowing air to the feet or windscreen only, and will not change position no matter what I do with the air conditioning controls. Air is still cold/hot and fan control speed still works, it is just the direction of the air that is stuck.
However, if I simply turn the car off and then back on (quickly) then the the aircon will go back to working perfectly again. Alternatively if I do not want to turn the car off and back on again, I can do a vent relearn with the car still running and that will fix the problem.

The strange thing is that the issue where the air gets stuck blowing to the feet or windscreen is temperamental and only occurs sometimes (but I'd say on average it happens 50% of the time). I have not been able to find a pattern as to when it will occur - it just happens at complete random. The only thing I have been able to deduce is that it seems to only occur once the car has been off for at least a few minutes.

Has anyone come across this same issue before?
Is it likely to be an actuator issue? I cannot hear any clicking or concerning noises coming from the actuators during the learning process. If it was an actuator issue then I imagine it would be the drivers side actuator which controls the face vent. Is there any way of being able to determine which actuator is faulty (if at all)?.

Originally I thought it could be a faulty HVAC module which is not delivering the signal to the actuators, but again, am not sure.

The only thing I can say is the drivers side actuator (the one that’s a son of a bitch to replace) is the one that controls airflow direction.

Do the simplest thing first, do a master reset by disconnecting the battery for 30 minutes.

I gave that a go but unfortunately that did not fix the problem
