    Recently with the heat wave, the a/c in my Prius has been acting up. It blows cold for a bit and then just warm air. The only fix I found to this problem is to turn off the car for a minute and restart it. It gets the A/C blowing cold again for a while longer. I checked the a/c gas pressure and it was good. What could be the problem?

    And check to be sure the radiator fans are coming on like they should be.

    Here’s an easier answer I discovered early in my ownership. If you are in ECO Mode, the A/C cycles off and on with semi-cold air. If you place it in Regular or PWR Mode you get constant cold air.
