A/C service with photos..
The only thing that kept me from sevicing teh A/C sooner was lack of access to a lift (or garage in which to jack up the car) and the equipment to do the job. Not to mention my lack of knowledge about A/C systems in general. Until last week I didn't know there are two pressure sides. <img border="0" title="" alt="[Eek!]" src="eek.gif" />
For the others, like me, who couldn't really figure out what to look for when trying to connect the hoses to evacuate the system, I am including a couple pics.
I found that the reason my compressor wasn't woking was the a broken wire coming from teh compressor.
Low Pressure:

High Pressure

$50 a an hour later my A/C was ice cold again.
I was planning to retrofit to 134a, but upon discovering the broken wire, learning that I still had over 1.5 lbs of R12 left, and no leaks, I decided to keep the R12 until it needs to be recharged.

I've always strayed away from a/c work until I figured out it's really not that bad. It's completely within the realm of most DIY's. A/C gauges and a good vacuum pump can set you back around $300 but use it once or twice and it'll pay for itself. Pick up a copy of the Mastercool a/c manual to get a understanding of how a/c works. Haynes has one too.
The 2 most important things to remember when doing a/c work:
1) Don't apply the high-side pressures to your can of freon. The metal can will explode in your face or hand seriously injuring or killing you. You fill thru the low-side connection. You don't wanna walk around for the rest of your life telling people you blew your hand off trying to fix your Porsche's a/c.
2) Wear safety goggles and gloves. One quick accidental spray of high-pressure freon in your eyes and your blind for life. If freon touches you, frostbite is a possibility, so wear gloves and long heavy sleeves. Not trying to scare you away....but just making you're aware of what you're playing with.
Any other mistakes will just cost you money, i.e. new compressor, more R-12 if that's what you have, or maybe an expansion valve.
