I have a working AC but I have to switch it off to climb “hills” I call it the booster button!

Check recalls and “warranty extensions” people. I just got my AC repaired by the dealer for free after dealing with a broken AC for a year plus because I found out there was a warranty extension due to a manufacturing issue.

Having a car that has a non-functional AC is indefinitely worse than having one that was designed without one in the first place (I’ve got both).

I’ve never owned a car with working AC. Half of them didn’t even have the AC option installed. I’ve just rolled the windows down and not been too bothered.
