Not sure if I've already mentioned this, but after replacing the radio and moving my hand around blindly in the dash the fan no longer worked. Not that it pumped cold air previously, certainly not; but now the fan would not turn on at the different levels. However I felt a plug that wasn't connected to anything just hanging in there and figured I'd just accidentally undone it. To fix this, I went to the hitman's site and looked under dash removal to learn what might be wrong. I found this picture:
The plug felt long and flat so I decided it went onto the orange piece. Maneuvered it back on and presto the fan works again. Doesn't pump air too strongly and it certainly isn't cold. Can't decide if I want to get a recharge kit, replace the compressor, or if it's probably leaking anyway and I should just take it in.
