HVAC Simplified Demystifying High Pressure vs. Low Pressure Ports

The high pressure port on the hard lines is smaller than the low pressure port on the drier. I have an R134 gauge set, which seems to fit the low pressure port ... Typical pressures when running are 30-40 on the low and 200-250 on the high side. These pressures will change based on ambient temperature and ... Very high on the high pressure side and low on the low pressure side. First check to see if the condenser fan is running at full speed. If ... Low pressure access is near firewall, around the center of vehicle. You have to remove carbon fiber brace, aluminum brace and some plastic ... the low side is closer to the firewall. and will be cold to touch. The orfice tube is locate between the 2 service ports. Of course you can add ... Which also requires bumper cover removal. My low pressure side read 40ish psi on a 70 degree day with Compressor running and air blowing ... Low side should be around 20-30. If your high and low pressures are always equal with the pump running, your expansion valve/orifice tube is likely bad. -Do not allow the low-pressure gauge to exceed 3 bar, otherwise liquid refrigerant can get onto the suction side of the compressor and destroy ... Both the low and high side ports are on the compressor itself rather than on the suction and pressure hoses as is more typical of modern cars. The 2006 A/C pressure switch is located in the high side refrigerant line, between the condensor and the expansion valve at the evaporator (in ...
