New to me 93 80 series. No power to compressor.

Ac button lights up
Ac fuse good and power in both sides of fuse
when I click ac button the ac amplifier black box behind glove box clicks. I have power on one wire of the ac amplifier wire harness when I push ac button.
I had a spare ac amplifier and swapped it same result.
I put paper clip on the pressure sensor by battery. No change


If I put 12v to compressor it clicks on. System has Freon and I get cold ish air when quickly apply 12v to compressor


Any easy to follow instructions on things I can check next?

Help me get this ok girl back on the road so she can hit 400k and I can give to my son

I bypassed the switch by battery. Jumped with paper clip. No change. Is there 2 switches? If so where is second ?
