Q: Four-wheel drive light.

asked by on

The 4-wheel drive light keeps coming on.

On an electronic four wheel drive system such as this one there are a few different things that may trigger a four wheel drive light. A faulty solenoid or motor on the transfer case, an inoperative front differential actuator, or simply a bad switch could all cause this issue. I believe it is also possible for the four wheel drive light to come on if a wheel speed sensor has a fault. However, this issue would also be accompanied by an ABS and/or Trac Off light. An inspection of the four wheel drive system by a qualified mechanic would be my first recommendation.
