Default A/C compressor died in blaze of glory

I'm not even bummed, this thing survived for 23 years and worked perfectly until today. I got caught in some cold weather and had to use the defrost. It was working fine until about 20 minutes later when I was on the freeway and the engine died after I pushed the clutch in to down shift. Got it started again right away and made it to a stop light where I saw the engine was surging at idle. Made it to my side street and it started to sound like a loud blow dryer was under the hood and it smelled like something was way too hot. Got it parked and opened the hood and there was a plume of smoke coming from the A/C compressor. I let it cool down for a few minutes and started the engine with the defrost off and it ran just fine with no noises or smoke.

How common is it for just the clutch to go out? Does anyone have a part number that they recommend? Or should I just find the part with the best warranty?

if you car is 23 years old its a 1994 the part number is 1136535 for the compressor, 6581043 for the clutch. Or just go to your local ac repair they will know what to do

Well I took the belt off and tried to spin the clutch and it is seized. That means the compressor itself is busted and not the clutch right? Either way it looks like not only do I need a new compressor but it would be smart to replace the condenser and accumulator due to bits of metal that have most likely regurgitated out of the compressor when it died. While shopping for a new compressor, I noticed there are HD6 and H6 compressors, which one is correct and what's the difference?

Just did a compressor in a 99 truck, not sure on the differences in the part number difference.

If you locked up the compressor I would replace the expansion valve and the accumulator if you want to keep the warranty on the new compressor. The compressor needs to be filled with compressor oil and will need to be spun by hand so you don't start the motor with liquid in the compressor. Then hopefully you have a friend with a AC manifold gauge.

Yes, I ordered a Denso compressor and expansion valve and some no-name accumulator from Rock Auto. Also getting a lifetime warranty condenser from local auto parts store. Didn't think I'd be spending this much on A/C parts this year.
