Car was idling and out of knowhere the car started blowing Freon out of ac compressor. Hooked gauges up to ac compressor and found low side pressure was max and high side at 150. Re charged ac system, upon start up Freon blew out of ac compressor again. Hooked gauged back up and noticed high side pressure slowly climbing and getting to max while low side was fine, noticed fan wasn’t on, turned max cooling mode on through MHD and watched high side go back to normal and Freon didn’t blow out of compressor. Finally once the car warmed up the fan turned on for coolant and oil cooling pourposes and ac was fine. The issue im dealing with is the fan doesn’t turn on when ac is on. Are there any components like relays or sensors that controls the fan when ac is on?
