Fan Clutch Issue

[Arr_G]

2016 cascadia, DD15.

Fan clutch is stuck in engagement and will not release.

Fan clutch replaced in the last 50k, can pull Airline and feed with aux air and the Fan clutch will release.

Used power probe and when applying power and ground to solenoid the fan will release.

When testing plug to solenoid neither power nor ground can be found.

Where does the plug start and get power?
I can not find an associated relay or fuse location.

Any direction would be appreciated!

could be the A/C system low on refrigerant and causing it to stay on all the time.
