By jumping the a/c pressure switch connector is the only way to get the compressor to work, also the switch inside the car must be off?

Have the A/C tested for leaks, I feel that you have lost most of the refrigerant.

I observed that my 1996 isuzu rodeo ac condenser is stained with oil when performing a refrigerant leak inspection. Now the pressure switch is not coming up except the two terminals are looped. Can anyone advice me on the possible solution?
