Auto Air Conditioning & Heater Repair: 1996 toyota camry ac, toyota camry, ac compressor

Question
The ac compressor on 1996 camry comes on when you turn the switch on in the car and then goes back off in 30 seconds.the suction goes to 26 psi and the discharge goes to 210psi. I had added freon and the bubbles cleared in the dryed. I jumped out the relay at 3 and 5 and the compressor continues to run and the suction line to the compressor gets cold and wet and the temperature in the car gets to 45 degrees. So I put the fan relay in place on the ac relay and the compressor still will start and then turn off.The ac dual pressure switch is suppose to open at 30 psi and 384psi so I am thinking this switch may be the problem . Do you agree or could it be something else?  THANKS

Answer
It may be but your compressor  may also have a sensor either underneath the comp. body or behind it.  This sensor sends a signal to the ECM to cut compressor on and off.  You need to check relay and see if you loose the ground coming from the ECM.  If you do that sensor could be the problem.
