My air conditioning works fine (I had Brian rebuild mu CCU-Thanks Again Brian). I have a 1991 and it's been updated to the new refrigerant type. However, there is a distinct hum coming from the engine bay whenever I use it. It definitely is related to RPM and gets louder/faster with engine speed. The belt is new and properly tightened. It could be normal for all I know because it's been that way since I bought it last year. Any experienced ideas appreciated. Thanks and Happy Motoring! (I did a search so no flames please).
Noise = Pulley or Air Compressor?

Use a garbage disposal drain hose from Home Depot to listen exactly where the sound is coming from. If the noise is only there with the AC on, then its the compressor.

Great link, Thanks. I guess your right though, If the noise is only there when the air is running, it would have to be the compressor. I was hoping someone would say "That's Normal". I wonder how long it will last before it breaks?
Thanks Again and Happy Motoring!

It is a good possibility that it is the belt tensioner pulley. I had to replace mine for just this reason. Listen like the previous replys say.
