Steps in changing A/C compressor clutch Help!!

[rayray97]

I am 99% sure my compressor clutch on my A/C is going out. I have a 1989 Buick Park Avenue 3800. I need steps in taking the clutch off and replacing it. It has R12 in it and I do not want
to change the whole compressor because it is hard to find someone nowadays that will recharge an R12 system.

So why not change over to R134?

Is it easier to change the whole compressor than it is to change just the clutch on the A/C. My daugher is using the car and she is only here for a couple of days and I just figured changing the clutch would be faster than changing the whole compressor.

Changing the whole compressor is much easier and also does not require special tools (however, recovering, evacuating, leak testing, and charging does). That said, how come you are looking to replace the clutch? What is wrong with the one in the car? Have you had it professionally diagnosed? If not, it may be that it is not engaging because of a low charge of freon, or because of an electrical problem (fairly common on older cars).
