so...take a razor blade and scrape away a 4x4 inch area so that the AUTO FAN doesn't have anything blocking the solar panels and VIOLA you just saved $1,700 on a factory installed useless option!
oh ya... and dont forget to go out every 2 hours to reposition the car to maximize your solar exposure too!! if any co-workers complain because you have to park sideways because your parking lot is not facing east-west, tell them its to help slow GW...that will convince them
