AC SOS

[Vik1318]

Hello Group,
I’ve been fighting my ac for longer than I wanted to . Have replaced 90% of the parts and I’m still having the same problem. Once temperature reaches above 90degrees engine fan (ac)stays constantly on and eventually shuts the ac down. Parts that have been replaced are condenser, expansion valve, compressor, evaporator including evaporator sensor, bmc. The system has been vacuumed and refilled.
I’ve also noticed my ac compressor only cycles when it’s cooler temps outside as well. The only other few parts I can think of are ambient sensor ( don’t know if it plays roll when it comes to the ac system) also ac relay.
TIA
