It gave me like .xx more mpg. I did see triangular clearings forming on my back window when there was condensation on it. Didn't even have to use my rear defrosters that much. Since I took them off, no more triangular clearings and much more rear defroster usage. Of note, using the rear defroster kicks on the AC, so you use more gas.

Huh?

You can run the rear defrosters with the AC/vents totally off. It's just a set of wires running through the rear window glass that has nothing to do with the AC at all (short of the button being with the AC/vent controls).

Now the front defroster is a totally different story, since it's conditioned air being blown on the windshield to defog/defrost it, which does use the AC...



Cool that those little splitters helped keep the windows clear though...
