The A/C amp is the A/C and heat control panel on dash. it has a computer in it and talks to the BCM on the CAN bus. If the BCM sees A/C switch on and blower on it will signal the ECM for A/C The ECM will look at your system low pressure switch and will then signal the IPDM module to turn relay on for the compressor clutch.
Possible causes
A/C amp (or subsystem and sensors)
BCM
ECU
IPDM
low pressure switch
Relay
CAN bus communication issues
Like everyone else said. Talk to the service manager and you should not pay a cent more to have it fixed. If the service manager does not help you, call the regional manager.
They should reimburse you the labor charges and discount you on the parts they installed. May I ask how much you spent at the dealer?
