let's start by checking for power at the compressor and working backwards to the relay to see where the problem lies

Today i am 8 hours away from this vehicle. Yesterday i could not drive it back home because of no A/C. I am trying to gather as much information as possible before i make the trip to go fix it.
Customer: replied 3 months ago.
I did connect gauges to it and it showed pressure. If i remember well, low side 90 and high side 100 without system on.
