AC not working, no power to compressor
 

So, here is the story. My 2010 ML350's AC just stopped working. After checking all of the fuses, I thought it was the compressor so I replaces it. Still no change.
The pressures on low and high sides are equal regardless of whether the AC is on.
Because there is no power to the compressor, i thought it was probably the pressure sensor so I relaces it- still no change.
Checked the fault codes from the AC computer and it showed a bunch of codes that were related to disconnecting all of the sensors. I erased the codes and after running the car for a while , still no fault codes
During this whole time, i keep checking the gauges and no change between the car on and off.
