I have an '02 Explorer. About 6 months ago the 4x4 dash lights started flashing and the 4x4 would not engage. Had it checked by two different people who could not get a code when checked.
There is a grey and black plug/connection under the dash beneath the glove box which, once separated and then re-plugged, the 4x4 will reset and work for a day or a week. Any suggestions???
