Yesterday, the A/C was working fine until I decided I didn't want it anymore and turned it off -- that was the end of its life. Now it blows hot air. Compressor kicks on, I saw it spinning, high idle starts. I've had the compressor replaced already (came out of a 95'). Haven't yet checked for pressures, but I don't think its that because it went instant hot. Usually when it need refrigerant it gets gradually less cold.

The fan at high speed makes a "brrrrrrr" sound.

Any ideas?
