    Hello and thanks for responding.

    Have a 2005 Prius with 210,000 miles. I really like the car. My AC is full of freon however it only blows cool. Maybe just too hot of a day? Please advise. Thanks

    How full? Could be a slow leak. I'd book a dealership appointment, be prepared to spend maybe $150, for them to evacuate it, check for leaks, recharge.

    In the interim, have a look at the sight glass while the AC's running (AC compressor and radiator fans running). You should see little to no bubbles as it running, and a swirl of bubbles when the AC compressor (and rad. fans) stop.

    Addendum: it's not "freon" btw, there's a new refrigerant being used, better for the environment. And I believe a special oil is required. I would not go anywhere but a dealership for this: using the wrong oil could be disastrous.

    That's the big radiator on the front, btw.
