Hi all, I’m not mechanic but I’m fairly handy when it comes to cars. I’ve successfully changed the head gaskets in my 2009 Subaru. On my 2008 Prius, I’ve changed the oil, front brake pads, rotors, front struts, both tie rods on both sides, sway bar links, wheel bearings, axle, etc. So now it’s time to tackle the AC that doesn’t work. The fans blow in the cabin but only not-cool air. I bought this car in the winter a few years ago and didn’t bother to check the AC until last summer and now I’m trying to fix it. I bought gauges and both high and low say 25 psi. I discovered the error codes by pressing the buttons on the steering wheel and came up with codes 23, 42, and 72. I am not gonna take this into a shop so please don’t suggest I do so. I would like to learn how to fix this myself. If anybody has any leads on where to start, I would love to hear suggestions.
