    As the title states the light that appeared on my dashboard in order from lect to right. Also my monitor has the word problem appear and a car with an ! In the center of it in the upper left corner. My car has stopped blowing cold air. What might be the issue. It all just happened one day whilst driving, it wasnt this bad a week ago. Simply the check engine and the circle with the exclamation mark and have not had the opportunity to check on it.

    An error code(s) has been stored in memory... As long as you don't disconnect the 12v battery you can get that code read for free at a local auto parts store. From that point there may be some sub-codes that you may need a phone app or Toyota techstream to get at... Let us know once you got some error codes and will help you chart a course to worry free driving again.

    welcome!

    it is often the inverter pump. if that is working, you'll need a prius aware scanner to read th trouble codes

    Nobody can help you from that description. You need a code reader that can read all the codes, not just the ones generic readers can read. I suggest getting a mini VCI cable and techstream and getting back to us with the codes.

    You can easily check the inverter cooling water pump to see if it failed. With your foot off the brake, press the power button twice. The inverter cooling water pump is located directly behind the driverside headlight and should be making a humming noise if it is running. There should also be some noticeable turbulent flow in the inverter coolant reservoir if you open the cap. (located just to the passenger side of the inverter near the firewall and full of pink fluid). Now, with that being said, just because it's running doesn't mean it's providing full flow, but if it's NOT running, you've found a problem that needs to be fixed.

    Checking it using this method prevents the engine from turning on, which makes it difficult to hear the hum and causes false ripples in the reservoir. No engine running=easy to check pump operation...

    Intermittent loss of AC is often a leading indicator of ICWP failure.

    The dashboard going black and the car shutting down while driving is a true indicator of the pump failing and blowing the AM2 fuse. You don't want that to happen...

    Got the car checked and received code P0A93: Inverter Cooling System Performance. So suppose that gives an idea but how do i know what's wrong. Turned on the car without the motor, and checked in the reservoir. The liquid in there seems stagnant, cant tell if it's supposed to doing something
