I have some issues with my 4wd system on my 98 LT Blazer (rhd) with the 4 button auto 4wd)

Everything seems to operate fine but it doesn''t actually drive the front wheels.

The controls buttons work and I can move in and out of all modes.
The TCCM clicks when doing this
I hear cluncks etc from the transfercase/gearbox when doing this
The Vaccum Actuator works and locks the front axles together in 4wd
The gear ratio changes when in 4wd low

But the front wheels are still not driven???

you can notice a gear ratio change in 4 low but its still not driving the front wheels? sounds odd...I''m sure someone here has a good idea.....
