I have a 2003 f150 with electronic shift 4wd that will not disengage when switched to 2 high. I checked both of my solenoids and the engage works but not the disengage. I checked my disengage solenoid on a battery and it works fine. I also tested the ground wire going to it and it is good. The problem lies with the positive wire going to the solenoid. It doesn't have any juice. Any ideas what the problem might be or where I would go to trace the wire next?

 

Connectors good? Controller alright? What happens when you switch it, does the positive get power at all?
