Ok so I have this Supra(non-turbo automatic) that I bought about a month ago. The previous owner was selling it because the engine had blown from a faulty oil pump so there was a new engine installed. It's not "new" but it's a different one. So when I turn on the a/c and set it to high there isn't one bit of air blowing from the vents. Car on or off it doesn't make a difference. Could it be a blown fuse or is it something else? Also, the car has no freon in it I belive but shouldn't it still just blow air no matter what?
