I've been experimenting with how the a/c affects gas mileage, have been turning the a/c off with the button and thought I would see an improvement, but have been rewarded with only very minimal increases in MPG.
To my surprise, I have found out that the a/c does not turn off when you have either of the defroster positions selected on the dial, even if you have the a/c button turned off.
Does everyone elses FIT operate the same way and if so, why would Honda make it so the a/c runs even with the button off? Is there a simple way to defeat this other than turning the fan to the off position?
Just be aware... if you think you have the a/c off and have the mode selector in either of the defroster positions, the a/c is not turned off even if the a/c button has been selected off (not lit).
