1999 dodge durango 5.9L
i have a 1999 dodge durango 5.9L 4x4. i havent done any off roading yet but my part time 4x4 light comes on the dash board when im in 2wd. ill pull over and put the truck into nutral and shift through the 4x4 gears, the light will go off for a couple of days or a week then come back on and ill have to go through the whole process again. can anyone tell me what this means thanks
