Hi my name is***** will be glad to try to help. Check and verify the system has full charge and if so check the pressure switches and wiring harness for a possible faulty pressure switch. See if the compressor clutch is engaged when the engine is running. If not it is likely a low charge or pressure switch/wiring problem. Let me know the results and if we need to dig deeper into this.
