I have a skid steer case tr320 2012 and i'm having issues with my a/c, i'm not getting power to my compressor everything looks fine, when I bypass the power on the compressor everything works and it blows cold air, got the pressure checked out and they are ok, checked all fuses none are blown and the 2 relays in the hvac unit under the filter are working... im running out of ideas... need some help
Check that your pressure switch or switches are working. They’re in the system to protect the compressor against too high or too low pressure
There's the bright red pressure switch right next to where you connect your high side line on the compressor. Then there's a thermo switch in the HVAC box behind your seat
