Trying to locate the low pressure switch for the a/c system, can't find anywhere. Have located low pressure port, high pressure port, and high pressure switch but can not locate the low pressure switch.

Most likely its the one on the compressor. If it is not on the dryer, then it is there

I believe the high pressure switch you are refering to is the pressure sensor which is mounted on a schrader valve. That is the only pressure sensor in system.

Yes, this uses a V5 (variable) compressor and doesn't have a cycling switch. It has a single, 3 wire sensor that the computer monitors with exact pressures.
