4wd issues
 

I have a 1994 K1500 4.3L V6 Vortec TBI that is giving me a headache! Any help would be greatly appreciated.

4wd is lever on the floor

4wd indicator light does come on.
Actuator(thermal, new) extends about an inch or so and is getting 11.94 volts
Key on engine off 4wd engaged, front drive shaft is locked in place
Yet no power to the front wheels.

I have no idea why its not engaging or what else it could be. Any ideas??
