Fan not working. Check fuse. 6 volts. Discounted wire moved to 12 volt source fan came on ? Is there a temp control. Switch. We’re is it. Apparently the fan is to run all the time. ? I have not replaced the fuse. Yet. Serm like it is the 100 amp one ? Any help thanks spot

The fan is a constant variable speed type fan, not on or off. There is a module that controls the fan speed which communicates with the ECM/PCM to control the fan speed in relation to engine temp. So could be a fuse issue or a module issue. A good tech is a must in this diagnostic situation. Good Luck.
