Cross post from ZB forum
=====================
Hi y'all...I'm new to this site and joined the forum as Holden and its dealers (surprise) have been unable to assist.
I've transitioned from a VF2 to a ZB (why you may ask-another story-have driven only Commodores for 13 years) and in the VF2, the HVAC was sweet. I could set the dial to a certain temperature, push the aircon button to 'Off' (the Aircon LED light would go off) and the air would still be cool without (I think) the aircon being on, eg. say 21 and it would be 26 outside. If I did press the aircon button to on (the aircon LED would light up), I would hear the compressor starting up and the air would turn from cool to cold.
With the ZB, this no longer happens. If you want cool air, you now always need to have aircon on. It will simply not blow cool air without the aircon on.
My question is what is the difference between the VF2 and ZB HVAC systems that the above happens?
Specifically, how is the VF's aircon designed such that even without the aircon on, it can still supply cool/cold air when the air outside is hot? Of course, depending on how hot it is outside, if you kept turning the dial down, the aircon LED would turn on at some point turn on but I loved the "sweet spot" before this point where you got cool air without the harshness of the actual aircon being on.
Question to Holden ("we're not mechanics here, call a dealer") and to dealers ("sorry, the ZB is new/not built to Aussie conditions/we didn't build it/too new for us to know/not trained yet etc. etc.) were not productive. Suttons City suggested I ask here.
Any advice appreciated, hoping there's an VF HVAC expert here!
