Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I am a Holden Tech, so I'll try to help you here.
A few questions, does you car have heated seats?
Do you have all the face vents open, 2 centre vents and both outer vents?
Do you have a dash mat, non-genuine?
And please don't rely on forums, info is always misleading, what they have mentioned to you is VE related.
Sounds like it has a lH air mix motor problem.
I would suggest take the car to Holden for vehicle wide DTC scan.
Mention your concern at the same time.
That is unfortunate for you that your local dealer gives you that as an answer.
It could well be a flap issue within the HVAC case, but a look at some HVAC data would reveal what's going on.
If you command cold, say 16-18 degrees, how hot does the LH side get in comparison?
40? or full hot?
