Do you guys know if the 4x4 indicator is supposed to be lit at all times? This is the light right next to the odometer that shows all 4 tires and the drive line. My light does indicate which mode the transfer case is in by illuminating the tires and the 4x4 systems seems to work fine but the light stays lit always. Is this right? The manual seems to contradict in a couple spots about this light Thanks!.
