i had this happen with my AC the day after i bought it (couple of weeks ago). they reset it and has been fine since. i'm wondering if they applied the latest flash.
also, i've noticed when watching my mpg avg that the AC seems to influence it in funny ways. for example, the mpg will improve a bit when on recycle/max vs normal - which is counter intuitive. also, sometimes when cruising and mpg seems very low (20ish) i'll switch the compressor to recycle, wait a few seconds, then back to normal and the mpg will jump up about 4 mpg.
finally, i've also notice the ac will occasionally increase and decrease (sounds like switching back and forth from max to normal) but i'm not changing anything and it's the manual version, so wouldn't think it would do this.
new logic for the AC sounds like a good idea.
