well if you need to replace the compressor that is a fairly easy job that you could always do yourself and just save your money. as far as the foghorn noise goes i dunno about that. maybe someone else can help on that one. good luck man.

claytonssho,

Where is the grinding noise comming from? The A/C compressor, the clutch surfaces, or the clutch pulley bearing? The clutch disk surfaces may be worn down so that the gap is too far out of specification to allow the clutch to engage.

Do you get the grinding noise when the A/C is off? If so, the pulley bearing is making the noise(most likely). The clutch assembly can be changed without opening the system.

As for the fog horn, look into the fan motor bearings and/or the "squirl cage" rubbing in the housing.
