    AC went out and I noticed the mag clutch isn't engaging.

    Questions...

    1) Where is the fuse for the Mag clutch? (Pics work great for me)
    2) If the Mag clutch is bad, does the entire compressor have to be replaced?

    I'll check the voltage on the mag clutch later today to see if there's power to it if the fuse is still good.
    I'm in Sacramento CA and it was 105°F a few days ago.... Hot AF!

    Get online, go to any genuine Toyota parts dealer like sparksparts.com mcgeorge toyota parts. Look up the diagram for the a/c compressor. You'll get your answers there, if they have the parts. Most likely is you have a leak, you'll need a pro to diagnose this as they have the dye (injected) or the refrigerant "sniffer" to find the leak.

    and I think the a/c relay is under the hood, in the fuse box..

    Wouldn't a leak result in low to no pressure on the low pressure line?
    I checked the pressure in the low pressure side and it's 3/4 up in the "Green".

    I probably shouldda mentioned that in the beginning......lol, ooopsie.

    OK, Fuse was fine and there was 12VDC on the clutch but the clutch still didn't engage.
    I don't know much about AC shtuff.

    Going into the shop tomorrow.

    thanks for the update, let us know how it works out! yeah the a/c can shut off the clutch if it has a leak, it does this from a pressure sensor. It's to protect the compressor. Or it's entirely possible the compressor is bad.. be interested to see what they find!

    UPDATE!

    Took it to 2 places and both said the compressor needs to be replaced.
    total cost $550.00.
    Stealership quoted $1200.00 - $1500.00.

    Blows cold air now. Not as cold as my Rav4 EV but it's adequate.
