I had ~40 PSI on my low pressure side but no AC. I bought a low pressure switch on a whim and put it in.
As of now, my pressure will rise to about 45 PSI, the AC clutch will engage for a second, disengage and drop the pressure, and continue doing so.
Playing around with different combinations of open/jumped contacts on the high pressure sensor plug yielded nothing. Clutch will not engage.
Clutch will engage and stay engaged with jumped low pressure contacts. I'm leery of running this for more than 10 seconds or so, so I cant tell if it's cooling the cabin.
What am I looking at wrong?
I do not have high pressure gauges. I'm using a cheap auto zone 134A hose and it says the pressure is normal for the ambient temperature
Thanks!
