I have a pet peeve and wonder if it's just me or if others have had the same experience? When I set my A/C fan to say, 3 bars, the display shows that it is no longer in automatic mode and says it is in manual mode. And yet it decides all on its own to raise or lower the fan speed which I find annoying because I know better what fan speed is comfortable than the computer, so that's why I chose to manually set it. I had my dealer check it and they couldn't get it to do it for them (nonsense, as it does it all the time) and since they didn't get an error code on their computer, they felt that the A/C is operating properly. That was in my 2008 GTC. My 2010 GTC Speed does it too so now I'm convinced it's a designed-in flaw or else I'm one unlucky sum*****. Anyone else have this gripe or know how to make it stop?

 

Hmmmm...haven't noticed that myself...but I usually have it in auto or off...I'll check it out for you.
