Confused 05 6.0 sd duelly 4x4 issue

[Randytodd2012]

First id like to say hello and ty for running this site i have an issue with my diesel and i hope someone may know the remedy.

2 days ago out deer hunting i had to go around a massive hole and proceeded to bury my duelly after getting it unstuck i had an issue getting it out of 4 low...which is all better now thank god.

but now since this episode as of yesterday morning i cannot get it to ingage in 4 high or low could it possible be a blown fuse that runs the switch or am i looking at bigger issues there is no noise nothing just wont ingage

any help would be greatly appreciated ..ty in advance

Well first I'd like to welcome you to FTF. Second, I'm going to move your post to the Gen. 1 Superduty forum where someone knowledgeable with Superduties will be able to give some advice.

Thank you for the kind words...

Is your truck a "shift on the fly" with auto hubs?

 

[Randytodd2012]

Yes it has the dummy turn nob but has lock hubs and autos i can turn them into lock or auto...

Does the 4x4 light on the dash illuminate when you put the switch in the 4 hi or lo position?

 

[Randytodd2012]

not now it doesnt it did yesterday morning i had to put it in and the 4x4 light came on but tonight when i needed 4 hi it didnt go into 4 wheel or anything no noise like it even tried no light...

 

[Randytodd2012]

one thing i should also mention is that after i got it out i had to back thru another good size water hole. water was deep enough to make the air filter need to be changed and i did that. i think i need to dry it out it has been non stop rain monsoons here in upstate ny and now temp went down today and now snowing so maybe its just wet and needs to be put inside to dry out?

We've got some real knowledgeable folks here that in time should weigh in on the subject but if I was to guess, you have a blown fuse.....If that's it, what caused it is the question. Is it just wet, could be or you could have knocked a connection loose too....Let's see what others might have to say...

The light not coming on tells me there is a power supply issue (fuse). The auto hubs are prone to vacuum leaks from the hub seals (especially after running through water or soupy mud. Do you only have defrost (no vent or floor)?

I hope so but like i said was working properly that 4.5 feet of water didnt help matters much but its a ford it can handle it..

Problem is, its a Ford, not a submarine.

If it wa submerged the shift motor may have water in it and froze not allowing it to shift.

 

[Randytodd2012]

no heater issues at all everything works normally but one thing i did see is when i turned on my dash lights the 2wd 4hi 4 lo lights didnt come on on the dash panel seems like the light is shorting out behind the dash panel

 

[Randytodd2012]

ok i will put it in our auto craft garage tomorrow and raise it up and let the heat circulate around it and let it dry out see if that helps. i do know 1 thing. it will never see stuff like that again. .

 

[Randytodd2012]

ty smokey i will have a mechanic take a look at the shift motor and maybe take that off and dry it out.

update
well i bought a new switch and put it in and still not working can anyone tell me where the shift motor is that may need to be changed and how much do they run in price?

If you're sure the power supply is ok (fuses) there is a 4x4 control module behind the glovebox. Theres 2 connectors on it.

I am having the same issue with mine. I checked all of my fuses and they are good. I think I am having vacuum problems also, I tracked the lines to the hub and they look good. I think I need to locate a vacuum gauge and check that. If you find a solution could you please post, I will return the favor. We might be able to save some major time and cash.

I did the same thing. I took mine out and got it dirty and now my 4x4 doesn't work. I sure miss manual hubs and floor shifters..
