Hello everyone, I had a slow leak in the AC system which I fixed. It was a loose schrader valve on the high side gauge port. Pulled a nice vacuum which was still good after about 1 hour of waiting, so I'm very confident the leak has been fixed. However, when I slowly introduce fresh 134a the gauge just goes up and up without the compressor ever kicking in. It stops at around 80 since that's what the pressure in the can is I assume. Every other car I ever had to fix the AC on, the compressor would have kicked in at around 40 to 60. I tried keeping the car in maintenance mode (ICE engine on) and also just in READY mode. No change. As far as I know the compressor runs off of the 200VAC converter right? So the ICE engine doesn't have to be on at all? AC is on in the car on full blast all doors open and on recirculation. I know the compressor might not come on because it senses low refrigerant but that makes a refill impossible. How can I "make" the compressor come on and do it's job? Is there an override of some sort for Priuses? Or the compressor is dead? Is there a way to check that without getting a new/refurbished one?
It should come on making a racket or not . Do now check fuses and inverter ac cabeling . Pressure switch unplugged? It's built into the metal line.
Prius AC is a variable pressure system. You can't accurately fill the system based on pressure; standard is filling the system based on weight.
