My transfer case shifts into 4 Lo but my front axle doesn't engage. Yet in 4 Hi it does. My pickup has the Auto 4 wheel drive system. I think its electrical in nature so I would like some trouble shooting advise or maybe a wiring diagram of the 4x4 system.
Do you
have the same problem?
Yes
No

It is most likley that the 4x4 switch has gone bad internally. I've had to replace several of them including on my own truck.
