How is the AC unit on the hybrid powered? The other day I was in a very slow drive-thru, which took a long time, and the engine didn't start for at least ten minutes. But it was a warm day, and the air from the vents never warmed up. That would seem to say that the AC compressor is electric. Is that correct? If so, is it powered off the 12V battery or the traction battery? My guess would be the 12V system, since I'd imagine it's easier to find a 12V motor than a 250V motor off the shelf.
