CHEVY 4X4 PROBLEM

2002 Chevrolet Silverado

Transmission problem
2002 Chevy Silverado V8 Four Wheel Drive Automatic 150000 miles

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.

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.
