Experiencing this common problem in my '06 when I switch to 4x4. If I manually lock the hubs, 4x4 works of course...and the defrost vents kick on.
But the funny thing is this. As I drive around the farm with the hubs in auto, I can climb a steep incline and flip the switch and the 4x4 will engage and work just fine. But on flat ground or under heavy acceleration on flat ground, the auto hubs will not work.
Any ideas why this auto hub system would engage while going up steep hills but not on flat ground?
