DIY: Unlink A/C from Defroster

[dreamteam]

I agree with Toast, had the same problem with my defrost, pulled the fuse on the air.
It's clearly marked and easy to get to........liked the results so well, that I pulled the fuse on the wife's '07 corolla. Suddenly, we are both getting better mileage!
Now, this won't work so good if you live in a hot climate........, up here, I won't have to put that fuse back in until spring.

People often forget that the A/C is turned on automatically with various settings. Pulling the fuse definitely works as an absolute verification that it is off, but in the case of the Yaris, doing the mod mentioned above definitely turns off the automatic mode, but still lets you turn it manually (without stopping to put the fuse back in).
