I've searched and found some post from '10 but no diag. My front diff or freewheel is not working as should. It's locked in the engaged position and the button for 4x4 does nothing for the front. I see the arm for the transfer case move but not the front. Swapped vac lines on the front and it disengages so I'm leaning to something electrical. Tried to check voltage at the 2 front solenoids and got 0V with switch in both positions. Thanks for the help
