95 sc400 A/C probles
So today i fixed a refrigerant leak on my sc400, i put the system on a vacuum and it held. Weighed in the refrigerant (30oz of r134) and the compressor will not come on by itself. I can jump the clutch out and it will pump and make nice cold air, but i get no 12vdc to the compressor without the jumper. I have tested the psi switch on the hi side line but i dont see one for the lo side. Can anyone provide some wiring diagrams/schematic of the a/c circuit? Im blind without a wiring diagram
Thanks
Thanks

put on vacuum for an hour, all factory with no mods. Cant see the dryer being a problem b/c it will cool with the compressor jumpered to 12vdc. Im having an electrical problem and not a refrigerant problem
thanks

Ok checked the codes on the climate control and came up with 21 (Solar Sensor open circuit) Will this prevent the a/c from not working at all? from what ive read if its failed it will only cool on low speed if the circuit is open/short. this is not my case because the the fan will go to all speeds but with no compressor cooling
