    2006 Prius
    Hello everyone,

    I am the proud owner of a late 2006 Prius with at about 218kkms (136k-ish miles).

    The AC was not blowing cold anymore so I went to a workshop for a refill of fluid.

    The air is now slightly colder (very hard to feel), nowhere near the expected result.

    Running the A/C diagnosis (hold Auto and Recycle buttons on the steering wheel and press the start button twice) only showed an 21 error (light sensor) but I was getting dark so...

    The compressor is turning on (I do hear it) and so does the blower fan (in front of the car). I also see the HV battery power going from 400-500W to 1400-1500W when I turn the AC on (measured with Torque Pro).

    Is it possible that something's clogged (condenser, evaporator,...) ? Any clues ?

    I'm going back to the workshop on wednesday but I'm quite sure they're gonna diagnose a faulty compresser (it's turning on and sucking power so I'll probably go to a Toyota Dealer afterwards).
