Technican: It sounds to me as if the AWD sensor is feeding a bad read to to the control module.E.G. It thinks you you should be in AWD when in fact you're on level dry ground. I don't see where the transfer case would be involved unles it was a manual change to AWD which I don't think you have unless there is a switch that you have to press to engage.If so, both sensor and switch need to be checked.

Owner: that sounds very likely do you have any idea where the sensor might be or where i could find out where it is?

Technican: I'm not for certain on this paticular model, but it should be on the side of either the tranny or transfer case. Best way would be to refer to a repair manual.If you don;t have one, I'm sure you can find one at one of your local parts suppliers(Pep Boys, Auto Zone etc.) Paul
