One of the reasons I bought my XV is because of its great fuel efficiency. I knew I would take a hit in the summer (I can't tolerate heat at all)... little did I know, I'd be running the AC all winter, too!
When you turn the climate control output to the windshield setting, it runs the AC. Right? Although the AC indicator doesn't light up, I noticed that on cool-ish days this autumn, when I ran the defogger, the air coming out of the side vents was cooler than outside air. I also noticed that when I run the defogger setting a lot, my fuel economy is on par with summer economy.
So, is there any way to control this? It is rarely necessary in my climate. It's helpful to kick-start the defogging process (I've been doing it manually for years in older cars), but not at all necessary to KEEP the windshield clear. And I hate having to flip the output back and forth between windshield and floor, just to control the AC. Is there a hidden computer setting, maybe? Pushing the AC button didn't seem to help. Worst case, is there a fuse I could run a switch to that would control it without causing any undue wear?
