HVAC is AC happy at moderate temperatures. Car under warranty - took to dealer - dealer called Buick tech support who admitted that many have complained about same problem but GM has no fix in the works.
When one uses the "Auto" button for climate control in a vehicle and sets the temperature to say 70, I imagine that person expects the climate control to attempt to reach that average temperature, turning on/off either heat or AC as needed to do so.
The Regal climate control does not. If you select auto, the AC is ALWAYS on.
