Does any one know what the expected low and high side AC system pressures are for a 2017 Civic EX-T when it is full on and the engine is at normal operating temperature? Also, what is the pressure in the system when the vehicle is not running. I know these pressures depend upon temperature and I have not been able to find any reference to them online.

Here is why I am asking. I am having the issue that many others are having. The air conditioning is not blowing cold air but only slightly cool air. The passenger's side air is noticiably cooler than the driver's side air. In fact the driver's side air vents blow hot and then warm air and never cool air. I have the gauges to measure the low side and high side pressures but do not know what they should be at various temperatures. I would like to troubleshoot this without going to the dealer. My guess is that some of the r1234yf has been lost. If my condenser had a leak like many others have had, then there would be no refrigerant pressure and no cool air what so ever. So now I am trying to determine if I have the correct amount of r1234yf in my AC system and I can do that knowing the expected pressures and temperatures.

Any Luck? Did you fix the problem?

Got the same problem with my 18 LX few weeks ago. Driver side is warm but passenger side is cold. I refilled it with Pro AC r1234yf (comes with charge hose and gauge). Now my AC’s blowing cold air. Hope it helps.

Early 10th models have a poorly designed AC condenser. Honda has extended the warranty on these parts to ten years. If you take it to a dealership and there is no external damage to it then it should be replaced at no cost to you. I have a 2018 ex-t and the exact same problem happened to me at around 40,000 miles. I was in and out in two hours and didn't pay anything. If you get it replaced just make sure that in the receipt they give you the new part number has A02 in it. The old, faulty condenser part number has A01 in it. If they give you any trouble tell them you are aware of the warranty extension and go to another dealership if need be. You absolutely should not have to pay to fix this.

Hazelhazela, if your problem is a faulty part then that recharge you did won't last you very long. I would get it checked out if I were you.
