Default 96 Olds Lss No power to AC Compressor relay

96 Olds LSS
I have 85lbs.static line pressure not running.
No blown fuses. Both fans turn on. If I disconnect the pressure switch (three prong)on the high side line at the compressor the fans will quit.I am guessing I am getting the signal from the dash control since the fans turn on. I do not have a pressure switch on the accumulator or the low pressure line that I can find.
No voltage at the relay on the firewall. I can apply 12 volts to the plugs green wire (86) pin going to the compressor and the compressor kicks in. Has cold air. If there is a cycling switch to bypass I do not know where it is.
AC light lit on the AC button on the dash.
All of the sudden problem.
