Why is my car AC Reading High Pressure?
Mechanics often misdiagnose high-pressure gauge readings in a car’s air-conditioning system. Most high-pressure readings are a result of the freon or refrigerant not cooling adequately. Insufficiently cooled freon automatically causes the pressure to increase.
Why is the air conditioner on my Honda Civic not working?
The air conditioning no longer works on the drivers side only blows hot air;the passenger side blow cool air,Honda has known a/c issues with the corrosive 1234yf refrigerant that impacts the entire cooling system. Service bulletin 19-091 covers the condenser however does not cover the compressor, clutch or coil and those parts are a costly fix.
What should the a / C gauge be on a Honda Civic?
If fuses were not the problem, hook up the A/C gauges to the system with the red line going to the high side (the small line) and the blue line going to the opposite large diameter low pressure side. The gauge should show close to 80 pounds on the blue low side and 140 on the red high side, depending on outside temperature.

Where is the fan on a Honda Civic?
The fan is under the passenger side dash close to the glove compartment. Use the circuit tester and check for power at the 2-wire connector on the blower motor (the key and fan need to be on). If there is no power to the fan, the fan is bad.
What happens when you stop the Honda Civic a / C compressor?
Discharge pressure abnormally high After stopping A/C compressor, pres- sure drops about 196 kPa (2.0 kgf/cm2, 28 psi) quickly, and then falls gradually. Air in system Recover, evacuate, and recharge with specifi ed amount. No bubbles in sight glass when A/C condenser is cooled by water.
Why does my Honda Civic air conditioner blow warm air?
It could also be that the evaporator is icing. If the AC is working too well, and the thermal limit switch doesn’t shut down the compressor at the right time, Ice will form on the evaporator and strangely enough, that makes the AC blow warm air until the ice has a chance to melt. But all of this is speculation.
What’s the air pressure in a Honda Civic?
Ambient temp Humidity % Inlet air temp Static system pressure 45 psi minimum Center vent temp ~30°F < ambient Low side pressure Typical: ~ 30 psi High side pres- sure Typical: 2.2 to 2.5 X ambient °F Pressure behavior when AC is shut off: High Side Pressure PSI Low Side Pressure PSI Center Vent Air Temperature °F Inlet Air Temperature °F 1.
