Re: electronic 4wd broken
I had the same problem with my push-button 4wd. That is a good idea to take off the electric motor and try engaging the transfer case with a wrench - it's marked where 4wd hi and 4wd low are. That should work - i doubt it is the transfer case. What was wrong with my electric motor was that a small plastic bushing had broken off and become lodged in the teeth of the gear driven by the motor. I'd take the whole motor apart and try to see if this is the problem - put it all back together with some grease on the gears to be safe and give it a try. Be sure to mark where the backplate with the electric sensors line up or else it will be difficult to get it aligned again (i've learned from experience and know how to align them again if this is the problem).
