What causes car AC pressure to be too high?

What causes car AC pressure to be too high?

An overheating engine radiator can cause the air-conditioning system’s pressure to increase significantly. Heat from the radiator transfers to the condenser and cause the pressure to rise due to the warmer refrigerant. It is possible the space between the radiator and the condenser has become clogged with debris.

Is the air pressure in the Kia Optima good?

I have a 2011 Kia Optima and when we turn the car on the Waite works great blows the temp it’s supposed to the air pressure is good. The only issue we have is that while we are driving it just stops blowing any air at all. 6 people found this helpful.

What should AC low side high side low pressure be?

On the other hand, there is possibly a huge leak when the pressure is zero. AC Low Side High, High Side Low: Why Does This Happen? The pressure reading from the low side should be between 25 and 30 psi and the high side between 200 and 250 psi.

Why does my Kia Optima blow cold air?

If the refrigerant charge is good, the compressor clutch is engaging, and the air only blows cold sometimes, there is most likely a fault in this sensor/solenoid. It’s job is to meter the amount of refrigerant flowing to the compressor, similar to an expansion valve.

Where is the low side high side low pressure switch?

The switch is located near the expansion valve. Use an Ohmmeter to find if it is giving the correct reading. Also, check if the compressor clutch engages and rotates the compressor when the AC is on. Similarly, the fan also has to spin when you turn the system on.

Why is the low side pressure on my car too high?

If you’ve recently added refrigerant to the system and are now seeing high low side pressure and warm air coming out of the vents, you may have added too much refrigerant. Evacuate the system and recharge with the exact amount of refrigerant based on the car maker’s specifications.
