Does anyone have a copy of a wiring diagram for a 2000 F250 or there abouts. I am looking for the 4x4 aspect of the drawings?

I am having a 4x4 issue. The transfer case motor is working. The fuses are working properly, and I have no leaks or loose connections with the vacuum hoses. So I believe it is a electrical issue.


Any help would be appreciated.

Do you have the combo manual locking hubs? If so, does the 4x4 work with the hubs manually locked?

I am having the same problem. And did the same motor test and replaced the dash switch. Posted a while back about ESOF. It will work for a while then won't shift in , or out, it varies. I too have manual locking hubs but still a PIA. There is a circuit breaker under the hood and two relays also. Make sure and check them. I would like to find a manual lever but was told they don't exist. My next step is the ECM or main computer. Pricey.

Well if the motor test worked the right way then you might have to replace the GEM module

Did you check for vacuum loss with a gauge?
It needs to hold vacuum and a gauge is the only way I know of to test that
