Does the pressure stay at 35? Is the compressor continously on? also Found that on my 87 there is no High pressure switch, so you probably do not have one either.

I finally got around to fix my ac as well. I put the dye in and like i said and had better luck at night It looks like i got it all over the place because i had some on my hand. But was able to find the leak. I had one leak on the fittings. Mine was actually missing the o ring, so took all the fittings off and installed new orings on all, just in case. At this point i also installed a new orfice tube(1.99 at advance). Put the system back together and pulled a vacuum to 30 hg for about 45 min. Dropped some freon in their and checked for leaks... Got no leaks and AC is kicking...The key is to find the leak. The dye works...it has a slight green tint...hard to explain but looks like the dash lights ....Its not going to POP at you you have to look for it
