That’s the only reading that matters. 50 psi isn’t bad depending on the ambient temps but seems high. Get a sold low and and high side reading and let us know. Also the ambient temp.
Alright so I did a bit of monkeying around on the car:
Without any switches jumped: the reading was at 56psi
With both hi and low switches jumped: it dropped a bit more to 52psi and the compressor ran about a second longer.
Both times only the compressor cycled once and stopped
Car currently has 2 full cans of freon in the system.
