Was riding at wildcat this past weekend and noticed my 4wd quit working. The button was pushed in but the indicator light was not on. Everytime you click the 4wd button there's just a buzzing sound in the front end. Back tires pull fine. Possible actuator?? Need some help!

 

Sounds like the servo has taken a poop to me.
