I have seen some posts about 4X4 problems.
Does anyone have some wiring info?
I have a 1998 K3500.
The 4X4 worked when I bought it, then ran into some problems with wires.
Turns out, the dealer forgot to secure the main wire bundle that goes
behind the engine across the top rear.
It hung down on the hot engine, and fried some components.
After all the repairs, (7 bad wires, new PCM/ECM, and fuel injection
regulator module), now the 4X4 does not work.
I can hear it engage when I move the shift lever, but do not get any
lights just below the 4X4 shifter indicating which mode selected.
I assume the magnetic solenoid is not getting the voltages needed to
make it work.
Any one have any wiring info?
Thanks for any assistance.
PS. Chilton's is useless.
