A/C issues
A/C issues
I'm pretty convinced the compressor clutch is failing me. If I sit at a light too long the cool air stops and the A/C light blinks. Once rolling again, I can push the A/C button twice and the cool air kicks on again. Has any one had dealings with this? I checked the pressure and I'm at a solid 38psi however it's not cycling, which I find very strange. Does anyone have a spare compressor or know the best place to buy one? I found one at a salvage yard for $200 but you never know what you are going to get. It was 110 today so I have to figure something out quickly. Maybe just buy a GTE swap and use the one that comes with that. 
Compressor is gone, not just the clutch, if that was the case, it would only cost like 20 bucks to fix(I lie, but it wouldnt be expensive). Seriously though, check ebay, I know it may take a couple days to ship and what not, but they are the cheapest there. You will probably need a dryer too.

If it was the clutch that was gone it would slip (burn the friction material) and you would effectively sieze it. Several things could happen, but most probably one of thse two: #1 - the armature of the clutch could "weld" to the hub ie: your compressor would be working all the time, or #2 - your clutch could be on its way to point #1 by slipping.
The only thing you could check with the light is if it engages or disengages, but then again you can hear it as well.
I'd do a pulldown vaccuum test to check for leaks first.
