4WD Slipping out (I think)
I have a Chevrolet TrailBlazer LT 2008
When I select 4WD, 4Hi or 4Low from selecter switch it works (LED On and I hear it changing underneath). I then start to drive but few seconds later the steering goes all weird and un-drivable. No faults displayed on dash and I then put back to 2WD and works fine.
I checked the driveshaft from transfer case to front diff. It rotates freely when in park and no weird noises. I would like to see if the driveshaft actually rotates when 4WD selected but I don’t have a GoPro.
Ive read about a lot of issues with the selector switch but that part seems to work fine.

Thanks. I believe the electric actuator is located on Transfer case. I see on some earlier models there was an actuator under battery.
Good idea removing and manually selecting. At least I would know if it’s the electric actuator.
Ive seen a lot of info saying if the actuator is the problem a service 4WD light comes on.
