I have a 2011 Jeep Liberty Sport 3.7 L engine (gas) that the 4WD wont’ engage. I don’t hear the clunk underneath when trying to go into 4WD. This only happens when the 4WD, 4low and Stability control symbol lights up on dash board. In addition it shows “ESC OFF” in the odometer mileage LED. Anyone expert enough to figure this out?
