Does anyone know which fuse would control this? If it's a separate fuse I'd like to pull it so it doesn't get turned on on accident. I have a rear window advertising wrap that it could damage. I already pulled the rear wiper fuse and really don't need it or the heat. I looked in owner's manual and found the wiper fuse but no mention of the heater. It's probably on with something else that I need. I could do trial and error and figure it out but thought I'd ask here first.
