Default Can't hunt down A/C leak

I have charged my a/c and used the dye "shots" and I can't seem to find the leak. Used a uv light and goggles. A/C works for a week then goes warm.

Any ideas?

Should be visible using the dye - look at the high side pipe that connects to the condensor, usual spot. Also around the compressor. Oil leaks out as referigerant does, look for that too.

Ok I'll look a bit better. We are recharging it again tomorrow. It will be the first time I have charged it since last summer so maybe we will see something this time. I'll update tomorrow with the results

We had a T-bird doing the same thing and the leak was behind the pully for the compressor itself but we couldnt see it even with the dye. We finally used a small hose and could hear it leaking out. Also all the grease and dirt build up on the compressor could have been hiding it.

The leak is coming from the compressor. Not sure if it's cracked or what. I'll have to pull it off and inspect it. How much for a new or used one?
