Want this question answered?
You will be checking the pressures at the same time......
Put your blue hose which is your low side to the low and red which is high to high ac then read your gadges
High side and low side refer to the pressure in the ac system. Ie The high side is the high pressure line and low side is the low pressure line.
I want to know where the low and high pressure ac sensors are on a 1993 camaro
Hey C==You really need gauges to be sure you don't overcharge the system. The low preasure outlet is by the accumulator. You charge it through this port. GoodluckJOe
the low is always the big hose and the high is the little one
The low side will be on the accumulator and the high side will be on the discharge line.....
Try checking the low pressure switch.
Check the low and high pressure switches, the AC fuse, and relay. Any of these can cause the AC to not get power to the clutch as if the freon is too low.
the low side of your ac system is the big of the two, the other is the high side, big one has the blue top and the high has the red one.
You can't.
either its low or too high of pressures
