I charged my 1986 V6 with the fluorescent dye and using uv light and glasses I have been trying to locate the leaking point in my air conditioning system.
I used this technique some years ago to locate the leaking O rings where the hoses connect under the air cleaner area. I have searched the compressor, under dash and engine compartment w/o finding any other dye leaking. I had charged the system a couple of weeks ago and it blew cold air, now just ambient air.
Any ideas for the usual suspects?
Thanks.

I just found my orifice tube connectors were loose. Go around with a wrench and see if any of yours are loose.

In the front compartment, under the accumulator, toward the driver side. Check the accumulator connections also.

Mine leaked out at the compressor shaft seal behind the clutch. I just kept refilling it (back in the days when R12 was cheap and plentiful) until the seal finally wore out enough for me to find the leak.

I looked at the places mentioned w/o any sign.
Of course the sealer/dye could have sealed it up but not with my luck.

Compressor shaft seal is the most likely place, followed by compressor hose connections. My leak ended up being the worst possible place, the under car lines. The line had corroded, and leaked where it attached to a bracket under the front compartment tub.
