It's the fan control relay and it's located under the passenger side headlight. In order to get to it you have to take off the front bumper and facia OR do what I did and take your dremmel and cut a hole in the plastic under the headlight big enough to remove it. It's not easy to find but trust me it's there and it's definately your problem. I just covered the hole back up with a scrap piece of plastic and some duct tape. Works like a charm!
