2002 Chevy Tahoe. 5.3 flex, Push button 4wd.
My 4wd is not working. The 4wd selector indicates that the 4wd is engaged but I have no front wheel drive. The actuator is new and I can hear it working. The Service 4wd light has only came on once, just recently on icy roads. The truck was is 4wd Auto and when the truck tried to engage the 4wd the Service 4wd came on and locked out the 4wd selector switch. I had to shut off and restart to gain access to the control. Thank You.
