My compressor clutch and/or compressor was making a racket for quite awhile and now I believe it is completely dead. When I turn the A/C on the clutch does not spin at all and the radiator fan does not come on anymore. How can I make sure this isn't an electrical issue. Also I have heard that I should be able to spin the clutch with my hand and the compressor will pump up and become to hard to turn. Before the clutch stopped coming on I was able to do that. Now when I spin the clutch by hand it never pumps up. Is the clutch mechanically connected to the compressor? So does that mean the compressor could have ruined itself too?

Car is 1985 Daytona still charged with R12 and yes the system is charged.
