newb ESOF

[TBurton]

Ok, I've looked over a lot of other posts still not finding a answer. 2004 f-250 6.0 ESOF turn switch to 4x4 nothing happens, no light on dash (although its lights up on start up) fuses are good, swapped relays already, no power to transfer motor (checked with multimeter) any suggestions, I've check all fuses with meter (all the ones listed for 4x4 in someone Else's post) any suggestions what to check next besides wiring?

Pull the switch panel out and see if the wiring connector is even connected to the switch at all. Check the basics first.

Mine crapped on me once, the dealer told me that there were TWO relays/switches/WTFE. Rather than look for them, I turned it in because it was still under warranty. Sorry that I can't be anymore help than that. ON the up side, you weren't in 8" of water when you figured this out!

I'll have to check the switch this weekend, right now the dealing with the alternator (again) should have that figured out by today, then back to the ESOF.

A 1/2" ratcheting torque wrench will enable you to reach serpentine tensioner. Set at max to prevent holding after it clicks. The aft radiator clip on shroud must come off for this. You can see square hole, but you're going to have to feel the wrench into place. Once in, push away from you, remove belt, EASE the wrench back, repeat for install. Thats how I do my single alt 03 6oh.

ok, alternator fixed. how do you get to the esof switch in dash, does it pop out? take dash apart?

[TBurton]

ok, switch tested good, have the right amount of ohms for each position.

My dashboard switch also checked good electrically when my ESOF failed. As I stated earlier in this thread, there are TWO more relay type items between the dash board and the shift motor on the transfer case. I apologize for not knowing more, this was a warranty fix at the dealership and they told me they had to change both of them out.

I checked the two relays by switching them around, no change, also no corrosion is present

I'm not following your logic path here, how does switching them around tell you anything? If they both need to be working to operate the shift motor, and one is bad, it won't matter if it's in spot A or spot B. I'm no electrician, but that's the basics of how it should work.

Speaking of which, have you tested the shift motor on the transfer case itself?
