Transfer case motor wiil not shift out of 4 wd hi. the wire harness from this transfer case motor goes to three seperate locations. Four wires go to a connector at the rear of the transfer case just below the drive shaft going to the rear differential. Three wires go to a connector just to the left of where the transfercase motor mounts. The remainder of the wires go to the transfer case motor. I dissambled the transfer case motor and the armature and brushes are clean, the motor does not smell burnt. With the transfer case motor was dissambled I checked voltage at the orange lead and read 11.5 volts at that point and when the selector switch was moved from auto to 4 hi I could hear a relay coming in and out for about 5 seconds and when the relay quit clicking the voltage went away. I was told it could be the switch in the dash or the module behind the radio or still possible the transfer case motor
If you are testing the voltage at the mtr on the tansfer case and you have voltage all other parts are working . so that leaves two things the mtr our the coller that engauges our disengauges the tansfer case you are almost there in solving your problem good luck kdc744
