My car does not have an aux electrical fan at the front of the radiator. I have no idea why. It's an '04 4.4i.

I am skeptical about the refrigerant level because the behavior has been the same before and after I had the system re-charged and the problem has existed for nearly a year. If there was a serious leak, I would expect the AC to not work at all. But right now, once the compressor does start, the air is super cold and nice.
