I'm sure Buick (well, if they're smart) will introduce a haabhctck Skylark or whatever they call it if the sedan is a sucess. Why not, when the design is done and the tooling is available? There are both two and four door hatch versions ready to go. Particularly if say Ford moves a lot of haabhctck Focuses. But historically of course hatches in the US haven't sold as well as sedans, but maybe we're getting smarter. Corollas for instance are hatches in Europe but sedans here. On the other hand, the Versa hatch is doing well vs. the sedan. Maybe the Mini and Fit, only coming in hatch form, have also helped the image. Speaking of badge engineering, in England Opels are sold as Vauxhalls. The difference is actually limited to only the badges, unlike the various Buick-Opels which have a different grill in the same opening. Everyone in England knows they're identical to Opels, but they like their Vauxhalls and also it indicates they were made in the UK. Most Buick buyers probably won't even know, and no one will care. Those that do know will only be more attracted, if not consider a Buick at all, because it is a German design. You know, like BMW and Mercedes.

I do believe that thing has a vacum oerpated switch. As well as a host of sensors and relays. The A/C is designed to run even in heat mode, the compressor cycles. Could be anything from the high pressure switch to a relay or even a blend door not operating.
