you can pull the AC with the PS intact, there are 4 long bolts holding the AC compressor on. Take off teh AC lines, loosen the 4 long bolts (there isnt enough room to remove the bolts, but just loosen them enough to get the compressor off), then pull the compressor out from the front. You may have to remove teh battery, and battery tray to clear the compressor. It shouldnt cause any check engine lights at all

Good luck with the condensor, it doesn't look like it would want to come out to me. Do you have to take the front end off or something?

There are 6 rusty bolts and a pipe holding the cooler panel in front of the radiator in place. If I'm not mistaken.... The bolts take forEVER to get twisted all the way off but don't give up. You'll need to get the hood latch,resevouir tank and whatever else is in the way out of the way to pull it upward out of the bay. Just cut the pipe. My pipes were locked together pretty good. I have everything pulled except for the compressor.

I have my A/C and PS removed. I'm going to be snapping some pics of my engine bay in a few minutes, so I'll snap an extra pic for you when I go to do that.

The PS is connected to the huge mounting bracket, and is not connected to the A/C in any way. You'll probably have to unbolt the PS to get to the A/C compressor, but you can bolt it right back up after the A/C is out.

For the condenser, remove the hood latch and coolant overflow. From there it should just be 4 bolts. Pull it our from the top because there's a metal lip that stops it from coming out the bottom. It may be easier to get the condenser out if you unbolt the radiator.

You should depressurize the A/C on the low pressure side. There's a valve that looks somewhat similar to a tire valve on an aluminum A/C line near the top of the engine bay. It sticks out like a sore thumb. Unless you've freshly charged your A/C, it shouldn't take long to depressurize it. Technically this is an environmental hazard, and also it's probably not a good idea to breathe the gas. Mine discharged in about 3 seconds so I didn't really have to worry about anything. If you've freshly charged your A/C or suspect it's going to take a while to discharge, you might want to take it into a shop that can do it in an environmentally friendly way.

When the system is static, there is no low or high side, the entire system is at equal pressure.

I'm 99% sure there's no way to use the condenser as an oil cooler, otherwise I think everyone not running A/C would already be doing it. Pulling out the condenser isn't hard, just remove the hood latch and coolant reservoir. You can unbolt the radiator and move it back a little if you need a little more room.

I managed to remove my A/C with all the lines intact, but then again I did some removal with no engine. The fat insulated lines that go to the compressor have a mount under the battery box. The mount will probably break off after enough abuse. Mine broke off just after we got the bolt out. The bolt is really tough to get out because the rubber means it wiggles around all the time. If you're not up for the challenge, a hack saw will make short work of the lines.

Here's a pic of the condenser removed:
