    Most likely the actuator on the front differential is malfunctioning. First check the fuse in the fuse box under the hood. If the fuse is OK, stand in front of the vehicle with the hood open and have a friend turn the 4WD switch on and off. If you do not hear the actuator clicking to engage, you need to remove the the actuator and replace it. Before you do, try softly tapping it with a rubber mallet as your friend switches on and off. Sometimes this will release it. If you rarely use 4WD, remember to engage it at least once a month as the actuator needs to be used frequently to prevent it from jamming. Good luck!
