Chevrolet 1500 Silverado 4dr the service light on in message center what needs to be serviced

Hi There, This is a known problem with many of the Chevrolet trucks and SUV’s that is often times related to the 4WD switch becoming faulty and/or some of the wiring being corroded. I would suggest having a professional from YourMechanic come to your location to take a look at your 4WD switch to determine what may be causing this light to come on.
