99 first generation 4x4 5.4 triton V8 175k miles. The 4x4 light is now continuously flashing on and off while in AWD mode. Started doing it while driving on the street. Took it to an auto shop and they couldn’t immediately see if a code would come out and they’d have to do a full diagnostic. I made an appointment with a ford dealer on Wednesday to diagnose, but anything I’ve researched is pointing towards a sensor somewhere, hopefully. Anyone have a recommendation for a sensor I could possibly try first and replace on my own which might take care of the flashing 4x4 indicator. Seems to be shifting in 4 high and 4 low range just fine and I can hear it doing what it needs to do. Thanks guyths.
