Why did my AC compressor blow out?

OR-- the blow-off valve is failing and blowing off at too low of a pressure.

that is what I know about them o9n my own truck any ways... diff trucks may be different.

Good to know. Is the compressor okay after it blows out? Does that relief valve reset itself? Also where is the relay for the clutch? Gunna start trouble shooting I suppose.
