    I have a 2010 Prius.

    Just purchased recently and the AC is not working when summer rolled around.

    Things I've Checked:

    10A Fuse under driver dash side
    LOW AC line has pressue

    I do not hear the compressor kicking on or any sound when my AC is turned on. So I think it's the Compressor not getting power or not good at all.

    How do I check the power going into the compressor? There are two wire plugs going into it (an Orange plug and the black plug).

    Does anybody have a wiring diagram I can check with a volt meter to ensure it's getting power?

    New to the prius world so any help would be great.

    Thanks

    Does it have freon in it? You need gauges to check.
    Read the fuse cover, it will tell you which fuse to check.
    If you do a search, you can find other feeds about the a/c.

    Yes the LOW PRESSURE Line has pressure in it. MAXED to the red per my AC Refill Gage. When the AC is on, the compressor doesn't open the line for pressure to decrease and go into the compressor itself. I've checked the right fuse also.

    I've searched but I am needing the wiring diagram or which pin is power that initiates the compressor to turn on. I want to check that with a volt meter

    Power going into the compressor:


    There is also a fuse inside the inverter:
