It engages both low and hi 4wd all four tires spin it works fine for a while until it says its turning it off on its own. That’s when the service 4wd light comes out. After it says it’s turning it off it feels as if the transfer case is still engaged but front tires don’t spin.
I have a 2014 5.3 z71 Silverado. Been having problems with 4x4 I replaced 4wd actuator and transfer case motor. I continue to get a service 4wd on dash. Any help how to get this fixed really don’t know what else to do.
