Cat C12 fan stays on!

Fellass help me out.... i have a freightlner 2000 fld.... my fan stays on all of a sudden. I did a few things to the cooling system that i should point out. I replaced Thermostats 190 and replaced the electrical gauge with a mechanical gauge because the original read 12deg hottter. Now the electrical prong is just hanging there. No air leaks at solenoid. Although problem didnt start til 800 miles later .. i operated fan manually plenty of times .. can my A/C be messing with the fan? Any quick disconnects i can go thru to find my problem? I can deal with it il i get home but id really hate to burn an extra 100 gallons til oi get back. Thnx fellas.

 

Ok... i did narrow it down to the A/C being the problem. When i turn ac off, fan works as normal about a minute after. I moved around some wires to sensors anything leading to the a/c and the accumulator . Now my fan works fine half of the time while running a/c... if i know wich one is the high pressure switch i can zip tie it like u said..

I did turn the key and operate the fan yesterday before gettin ur reply ... the fan did not enage/disengage at that time, but cant remember if the a/c was in the run position at that time. Right now it seems to be working ok, but i know the problem isnt fixed just yet
