Where is the low pressure side AC port on 2006 jetta 1.9 TDIRead more: Where_is_the_low_pressure_side_AC_port_on_2003_jetta_1.9_TDI
the low side port is the smallest of the two, just find the ac valves and which ever one is the smallest is the low side. on the 134a it is the opposite way if you converted. The High Side(High Pressure Side) is always Smaller and the Low Side(Low Pressure Side) is always Bigger in diameter, Always.
The low pressure side is located on the compressor. To locate the port, jack up the driver side and crawl underneath to locate the compressor. Add the freon to the port on the compressor.
The high side will not hook up to the hose
port is next to the compressor under the car...
It is located on the reciever\dryer by the passenger side firewall.
HIGH SIDE....YOUR VALVUE TO PUT IN FRE. SHOULD BE DONE ON THE LOW SIDE
The symptoms of a bad ac compressor would be a grinding or rattleing sound or a low pressure reading on the high side with a normal pressure reading on the low side. The low pressure will be about 30 to 40 pounds. The high side should read around 150 to 200.
The low side ac port should be on the side of the passenger side of the firewall. It is mounted under the battery harness.
