A/C clutch
I'm having issues with the a/c clutch on a '71 cutlass supreme convertible. I've never had to work on an a/c unit, so I'm looking for some advice.
The pully on the a/c clutch spins OK. However, whenever the a/c gets engaged, the clutch locks tight and the fan belt just smokes across it (wonderfull smell). When the a/c is turned back off, the clutch spins freely again.
Normally I don't worry about it. With the car being a convertible I almost always have the top down anyway. It just bothers me.
Could this just be the bearings, or a problem with the clutch itself. A friend of mine said to just spray some silicone into it, but I would like some other opinions first.

It's the original R-12 unit. It has never blown cold in the 6 months that I've owned the car. I was planning on having my local garage run a preasure test on it to check for leaks anyway. I just have not gotten to that yet while I was working on other things more important to keeping her on the road.
Like I said in the prior post, this is not a world ender for me since the car is a convertible anyway. It just bothers me that it does not work.
But on the bright side, it gives me something else to tinker with.
