I'm a certified ASE tech, and need help. Head pressure's are fine, temp switch bypassed, but the system is still short cycling. The EVAP thermistor is all thats left besides the a/c computer. How do I know if the problem is the thermistor, or the computer?

INSPECTION
Start the engine.
Turn on the air conditioner.
Using the multi-tester, check the resistance between terminals 1 and 2 in the thermistor.
