07 pacifica AWD light comes on
Hi all. I am new here and have a question. My wife drives a 2007 Pacifica AWD. The AWD light will sporadically come on and stay on until the car is shut off. After turning the car off and back on again the light is not lit. The manual says that when this light is continuously lit the AWD needs serviced. The problem is, by the time we can get it to the dealer the light is out and they cannot pull a code. This happens rarely, maybe once a month, but with winter coming it is a concern. Oh, and I have never experienced this occurrence myself. I am taking my wife's word on it since I do not drive the car very often.
