Try an extra ground to the compressor. Sure, it should automatically ground through the mounts, but weird E36 M3 happens when we take apart and reassemble.
Its a long shot, but cheap enough to try.

Dumb question. I gather that it's a constant run compressor like so many manufacturers are running nowadays. Does applying power to it OPEN the solenoid? Meaning do you apply power to make the compressor bypass?
Doesn't run with the plug unplugged either. So.......no?
Okay, fair 'nuff. Gotta use scientific method after all. If it no worky with no power and it no worky with power applied, then it's probably NFG. I am assuming here that it isn't a variable orifice H-block kinda system, because even if it was and the H-block were so upgeberkt (nice intersection of pidgin German and GRM censor, there) that it was stuck wide open, you should still see a pressure difference were the solenoid slammed shut.
So, yes, the Magic 8 ball says "Signs point to failed compressor". Fortunately you live in Texas, it doesn't get very hot there, right? So you can do without A/C for the time being.
Incidentally, I wish we had 9-letter license plates so I could get "upgeberkt" on my next German car.
A giant CONGRATULATIONS is in order here. I know the feeling from installing that Celica motor and the rush when it fires up right the first time, it's indescribable.
On the A/C issue. Looks like with the newer 2002+ systems the AAC module will stop the compressor from coming on if a low or high pressure code is stored. Only after the code is cleared will the compressor start again.
Check this post out on the Merc forums, it's for the M class but should pertain to the R class also and may provide insight into your issue.Linky
Again congrats on the long time coming successful start up!
I found this video and thought it might be helpful just for a quick general familiarization.

I also found a thread from a guy with a w211 here and he was able to snag a solenoid of of fleabay here for about $60.
unfortunately I couldn't find one specifically labeled "R63" anywhere but I was hoping it'd be a semi-generic part that wouldn't run ya $400

Came to say this. Check for codes in the climate control.
Congratulations on near completion! I mean.. The hard part is over. Now it's just the little stuff.
Been along following quietly. Congrats on this herculean feat! This may be soon, but now that you've accomplished this, there's little to prevent you from picking up a cheap neglected Italian exotic and giving it the appropriate engine-out service it deserves. Sayyyy... a Ferrari 355 with bad valve guides and melted headers? Like I said, it's probably too soon. But at this point, the way you wear your heart on your sleeve, I feel like I know how you think and where you're headed.
Huge thanks guys. I'll check and reset the climate codes before I start unbolting anything. I clearly need a better scanner for this anyway. It looks like the iCarSoft MB II should work for 99% of the stuff I'm going to do at home. No, it won't do the cool stuff like reset the steering angle or actually cycle things like the $$ systems, but it should at least let me see and reset all of the systems on the car. iCarSoft II on Amazon
In reply to Nader:
Are you saying you know where that particular Ferrari is? 
And thanks for chiming in in to encourage me, I'm sure my wife will be thrilled.

Spider or Berlinetta?

You are the gift that keeps on giving! Checking that out now...

OK... I apparently had a weird dream about this thread last night. It was realistic to the point where I was actually surprised when I opened it this morning and found no evidence or what I obviously dreamt about. I don't want to jinx anything, so I'll leave it at that.
I don't remember dreams very often, but when I do - holy cow they are weird. 
I'm sure you'll figure the AC out.
I had a 2003 BMW M3 with a non-working A/C issue that stumped my independent (and charged me almost $400 for the honor of not fixing my car). The compressor/clutch just wouldn't engage at all. I got a hold of some BMW diagnostic software and found that a pressure sensor/switch was reading an odd negative value. I had the system drawn down, replaced the sensor (and dryer), and re-charged. Started working immediately. I suppose there is no easy way to get a read out on sensor info...
Looks like you're already on it with the better code reader but my Vette had some climate control related codes that the torque app wouldn't pick up but the Tech 2 would.

In reply to mazdeuce:
Duece there is no electromagnetic clutch. Our compressors are variable displacement. All we do for diagnoses is actuate the compressor with the SDS and monitor the % of the comp and refrig pressure. Do you have a way to check for faults in the AAC( climate control?)
Nevermind I see you found a program.
Hey, Federal Mogul is running a contest looking for great stories related to part related failures.

In reply to MB_tech2005:
Thanks for chiming in. I've still got a lot to learn about how things work. In a lot of ways the hard mechanical parts are the easy part, interacting with the car is much harder.
And thanks to everyone who is setting me straight on how these compressors work and interact with the car. It's all good useful information that I hope helps more people than just me.

I think at least half of the silliness comes from saying the name Guido.Also, the name sounds Italian and making fun of Italians for their mechanical weirdness is a long standing tradition. If I somehow run across Guido in real life, I'll buy him a beer to apologize.
My Ducati mechanic's name is Guido. He's hilarious. For what he charges he damn well better be.
Autobooks-Aerobooks in Burbank has been following along since the beginning. We've even discussed the whole project with customers who were already aware of the thread. We've also turned people on to the forum to follow along on their own.
Wow.
What a journey... from "Hey guys, I found this weird unicorn German performance minivan, so I bought it!!!", to "Oh man, the dealer wants $57K to fix the manufacturer's dumb design..." to "Forget them, even though it's damn near impossible, I'll fix it myself at home!" and finally, "IT ACTUALLY WORKS!!!!"
Bravo, good sir! You've reached that legendary echelon many DIY'ers never reach: you fixed an absurdly complex hand-built German V8 in your home garage. Nice work!!!
