Four wheel drive problem
Hey Guys, I bought a 02 F350 7.3 95k, crew cab pickup, in October. I had some problems with it so I took it to the ford garage for a checkup. Problems before garage: Mirrors don't adjust, no start when cool, no 4x4.The garage had the truck for a week and fixed the glow plug solenoid which fixed the starting problem. They didn't work on the mirrors and they decided the 4x4 problem was a four wheel drive control module, but for some reason had not ordered it in that week and I needed the truck, so I said don't bother. Their price ~500 internet price ~200. So I ordered the module and put it on, no change. They also put a new motor on, no change. I found a schematic on the internet and started checking for current. I have no current going to the 4x4 switch on the dash from the dark blue or white/light blue wire. I also checked for current coming into the module and seem to have everwhere I should except from the red wire coming from the esof solenoid (according to the connectors diagram, this is supposed to have voltage at all times). No current to the switch is clearly a problem, but I'm not sure what is causing this since all the fuses going to the 4x4 module are ok, and there is current coming in everwhere except from the esof solenoid? I have read around forms and have some idea of how the system is supposed to work, so feel free to hit me with detailed explanations! All help appreciated, Thanks!
