Low Pressure Port / 1991 Cadillac Seville
2 Attachment(s)
There is one valve (blue) on the large diameter tube next to the fanbelt and compressor and there is another valve (black) near the driver side of the car, I know one is the High Pressure Port and one is the Low Pressure Port, do you know how to decipher?

:confused: https://www.cadillacforum.com/forum/...9&d=1247156700 unless you are a certified A/C guy, with the equipment, dont even think about touching this one. https://www.cadillacforum.com/forum/...0&d=1247156731 |
Ok so the Blue Port is the low pressure, thanks

Ok so I did everything properly and when I hooked up the gauge it read in the warning level at a little over 100, what does this mean, the dash says that the refridgerent is low but the meters read hot?
