I noticed over the past week or so that while running the air seems to be colder than normal and even with the AC off, it seemed to be putting out AC air. This morning the fan did not run. I discovered the coolant was extremely low, but don't remember when I last checked it. I added coolant. When I turn the fan on, I hear what sounds like a relay single click. The fan fuse looks like nothing I have seen before, so I have no idea if it could be the problem.
