I have yet to spend a lot of time on this (just noticed it during lunch) - but what should I look for (other than voltage @ the compressor from the harness, bad relay, bad fuse)?

Is the system filled with R-134? It won't engage if there is nothing to pressurize.

As far as I know - the system has been the best AC system I've ever had. I bought the car new and I've never had an issue with it (never opened the system).

I took the coil off - I can get the compressor to engage but it won't blow cool air.
Looks to be out of R134a or have a leak etc.
Where is the low pressure inlet for recharging?

Well, I took my sister's car in and the heat wouldnt turn on for her. The resistor needed changing, dunno if that's the case for AC's or not, but thought I;d share that, just in case it did help.
EDIT: nvm, I cant read >_>

it on the firewall near the drivers side iirc. When you charge it make sure you put some dye in it to see where it's leaking. They are never supposed to use any refrigerant if it does there is a leak that needs fixed.

It was indeed low on R134a. I put 2LB in it.
It must have a leak in it. The coolant I used has stop leak in it - we'll see if it works....
The car is 13-14 years old and has never been charged. I'm not inclined to look for leaks just yet as whatever I find will be expensive to fix. I have my fingers crossed that I was just low and will be sealed by the new freon.

Stop leak just clogs everything up. Put some dye in it and see where it's leaking it might be a cheap fix.

You dont want to use stopleak in the a/c system!
Most of the times the leak is from rock chips on the condenser, or damage due to running up on a curb or into something. There should be oily residue around any spot that has been leaking.
If you put 2 lbs in, it has a nasty leak and will leak out what you put in...just a matter of time.

Try and find freon without stop-leak additive - it's pretty hard.
I assume that I have a leak somewhere. The question becomes where and how big.
I've spent $30 in freon thus far. The way I look at it: if this fixes it, great. If not, I'm out $30 any my winter beater doesn't have A/C.
If the 2 LB leaks out by the end of the summer it's dye, yellow glasses and a black light time.... The again, I may just wait until next summer and spend another $30...
From my research the most common leak point is the seal around the compressor.
