Took it to my guy.. he has one of those big machines that does the refrigerant thing. He hooked it up, poked buttons, etc..

Long story short, the compressor appears to be shot.

Introducing refrigerant had the desired results.. the compressor cycled at first, then stayed on... but made a chattering noise, and produced air a little cooler than ambient.

He also pointed out that it had already been converted to R-134A.

Whats another couple hundred bucks, right? :D

Thanks for the help, fellas! Much appreciated!

As the only moving part, the compressor is the usual suspect. But you can't tell until you charge it up. If the rest of the system has no leaks then with a new one you are good to go. Just be aware that our cars have pre-historic AC compared to today's cars. Mine blows 35° below ambient and that hardly cools the Bonnewagon. In fact I have to stuff towels into the floor vents to force air from the dash vents.

Yeah, I knew they weren't the best, but something is better than nothing.

He didnt mention it leaking, no... which was nice.

I don't see it.

Im looking at: ACDELCO 1520229 {#01134355, 1134355, 88964872} GM Original Equipment; w/ Clutch - $178.89

Reman is $159.79.. Hell, I figured an extra $19 for New was worth it.

A lot of guys don't trust rebuilts but I have had good luck with them. The $99 Fleabay one I got for my '05 Sunfire works great. It is a rebuilt 4 Seasons from a guy in Florida. It even came with the accumulator and oil. The one in my Bonnewagon is also a rebuilt 4 Seasons that I got used from a guy on here in Chicago. Works great. Then the brand new one I have on my Jeep I suspect is leaking. So if the price is right I would go new but if you can score a super deal I can't complain with my rebuilts.
