2003 columbia with 12.7 . Fan constantly running

I disconnected the supply from the solenoid . Still the same as I expected . While the fan is running the air from the supply stops and when the fan stops air is blowing from the supply . I am heading to the junkyard to put on another solenoid ..

We will see .

 

Still the same problem with the fam solenoid from the junk yard . Wondering if they cross some wires by the Jake's. Normally and when everything was working , when I hot the Jake's and turn it off ( going down the rd ) the fan cones on for about 7 seconds and stops . I am confused

 

Trust me , with shop air the fan will stop . The guys who did the head checked the fan clutch and it was fine. The problem is the on and off air from the supply . For ex...I am sitting in the truck .i cutt off the truck and wait 2 minutes and the fan is not running intol around 120 psi and then it cuts on

 

There is one more an air leak in the dash and which I have been fixing . Not sure if that would also cause that

 

Took me all day, but I can get by with this fix.From the junkyard solenoid, I cut one of the switches' cable , and the one from the connector showing ground and run it with a ground wire against the frame.The other was positive, so, you know how that goes.The fan stopped.At least I still have a manual fan switch which works.I must have lost my ground when I needed it.Not about to crawl under the truck to check for broken ECU cables and connectors.Hopefully , I can manually turn on the fan when the AC is on.
