99 CHEVY 1500

1999 Chevrolet Silverado • V8 4WD Automatic • 150,000 miles

My truck seems to be stuck in 4 wheel drive, even though I never pushed the switch. The push button switch says its in 4 hi.

December 6, 2010.

Will it change to any other mode? Have you checked to see if there is power to the actuator on the transfer case?
