A/C repair
My a/c has been dead for a few months now. It died in spring which wasnt a big deal but now Its summer and summers here on long island are anywhere from 90 to 100 plus degress with high humidity. I also drive alot for work and being stuck in my benz with this weather sucks.
Anyone ever replace their compressor and refill it themselves? Think I could do it on a weekend? Tips?

yeah, I was refilling i when the car started to smoke. Shut off engine and the ac compressor was glowing a cherry red

Unfortunately I think the problem with my a/c is something electrical

In the works: A/W IC, adjust pump, turbo rebuild (w/60 trim comp wheel)

I was taking a look at that earlier today. Seems easy enough. the only thing I dont think ill have easy access to is that vacuum thing he was using.

Yes you will need a vacuum pump, just no way around it. You should flush the system just to be sure no bits of the compressor made its way around. My suggestion would be to flush it, get the replacement parts on with new o-rings, and a new receiver/ dryer, then have a shop vacuum it, leak check, and refill with r-12. 134 will not do very well, you will not be happy. I have enviro safe in mine, this is a propane mix, mostly r-290(refridgerant grade propane) This works very well, but some think it is not safe, so research and decide for your self.
With the engine off see if the compressor will still turn by hand, not the pullies but the outer part of the clutch. This will turn just the compressor. If it will not turn the compressor is toast. If it turns but does not have any "compression" than likely bad too. If you get a junkyard one turn it to check compression, should have some, and turn without any grinding, roughness etc.
