Is there a way to override the "A/C unavailable below 40 degrees" ? I was driving in the fog and rain the other night and the outdoor temp was 37 degrees. My truck was fogged up like crazy. Without the A/C pump available to dry out the air it took forever to defog the glass. I would like to be able to push my A/C button and run the A/C compresser whenever I please. Is there a way to do this?
