My Sierra 2500 has the push button 4wd selector to the left of the steering wheel. For the past several months, when I start the truck the 4wd indicator lights are illumninated randomly in the AWD, 2wd, 4wd high and 4wd low positions. The truck usually is in 2wd even when the 4wd is indicated, but not always. Just recently, none of the lights are illuminated, and the truck is in 2wd. The service "4wd message" shows up in the information center. Sounds like a bad switch/indicator, right? Has anyone had experience with this problem?
