The reason you have high suction is probaly due to contamination in you a/c system. To clarify contamination, I mean water, other gases, or anything else, there only two things that should be in your a/c system, refrigerant and oil, anything else is a problem and will change your suction pressure.

If you can prove these items are true, then you need to examine that your condensor is cooling and condensing the high pressure gas, the tev is working correctly, and your high pressure is normal, and cooling is excellant.

What is a po532 code on a 2008 hhr ss


DTC P0532: Air Conditioning A/C Refrigerant Pressure Sensor Circuit Low Voltage.
The engine control module (ECM) monitors the high side refrigerant pressure through the A/C refrigerant pressure sensor. The ECM supplies a 5-volt reference and a low reference to the sensor. Changes in the A/C refrigerant pressure cause the sensor signal to the ECM to vary. When the pressure is high, the signal voltage is high. When the pressure is low, the signal voltage is low. When pressure is high, the ECM commands the cooling fans on. When pressure is too high or too low, the ECM will not allow the A/C compressor clutch to engage.

Add fREON bird low


H stands for High Pressure and the L stand for Low Pressure.
The A/C system is split into two sides, a high pressure side and a low pressure side. An AC compressor is basically a pump, so it has to have an intake side (low pressure side) and a discharge side (high pressure side).

Just want to make sure that the a/c low pressure line is located high is the a/c low pressure located in the back of engine compartment and high for easy access


Typically the the low pressure/suction line is a bigger pipe/tube, as far as location it depends on the car. The bigger AC line is almost 99 percent of the low pressure. Usually on the cap it will say most of the times to there is a different hydraulic fitting for the low and high side. Most cars I have seen have a little tag that will say suction or low pressure line, and or discharge high pressure.

If you are re charging the gas, always use the low pressure side of the system.

1997 jetta ac works for one minute then warm air blows


check the refrigerant level. The compressor is running until the low pressure or high pressure switch switch cuts it off.

Running the unit without enough refrigerant will damage the compressor because the lubricating oil is dissolved in the refrigerant. This is the reason for the low pressure switch cut off--to protect the compressor from damage.

If pressure gets too high, the compressor seals will blow. Thus the reason for the high pressure switch. Too much refrigerant or too much air in the system (due to a leak) will cause high pressures.

If refrigerant level appears to be correct, then suspect trapped air from a leak causing a high pressure cut-off. If refrigerant is low, suspect a leak causing a low pressure cut-off.

I cannot differentiate between the low pressure and high pressure


This is a little A/C 101. Follow the A/C lines. All A/C systems have a high pressure side and a low pressure side. The high pressure side is from the compressor to the condenser coil on the front of the vehicle to the evaporator coil in the dash. At the expansion valve in the evaporator the pressure drops. At the expansion valve the refrigerant changes from a liquid to a gas. This provides the cooling. The low pressure side is from the evaporator back to the compressor. Usually the high pressure lines are smaller than the low pressure (suction) lines.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
