hey just trying to fix my wife's 4x4 before she slays me and turns me into her chaperone She has push button 4x4 and an np243. When pressing the button I don't hear the transfer case motor engaging. Any sure way to test this? All fuses check out, swapped the dash switch with a working one, and tested the front actuator with 12v and it dog dicked Thx. Please help. My life depends on it.
