05 F-250 super duty 6L diesel. When I have the AC on and then switch to 4X4 the air flow leaves the AC vent and goes to the Defrost vent. The only way to make it go back to the AC vent is shift back to 2 wheel drive turn the engine off and restart the engine

I had the same problem with my '99 F250 with automatic locking hubs. Are you sure the hubs are locking? Mine stopped working on auto, I haven't had any more trouble with the A/C but I have to lock my hubs manually when I want 4 wheel drive.
There is a big yellow O-ring on the bearing assembly that makes the seal for the vacuum. You can take the bearing assembly off clean it real good, replace the O-ring and that will fix it for a while. If you use your truck off road alot it won't last long. I suppose it don't take much dust or dirt to break the seal of the vacuum.
I personally would rather get out and lock my hubs as to change those O-rings again! Good luck

Mine does it sometime and sometimes not. Did today after I could not get the Driver side hub to movve from free to locked. Bang on and never budges. But it does the A/C to defrost all the time in 4wd. Is the O-Ring cheap? Was glad to hear someone else has had this weird issue.
