09 gmc sierra no 4x4
hello, my 09 sierra is killing me... have 5.3 floor shift 4x4 today got stuck in my driveway pulling it out of shop, floor shifted into 4x4 and light came on but nothing happened only back wheels, tried the 4x4 low and still nothing? the stability trac and trac control instrument lights on dash. not to sure where to start any suggestion on this would be great...

it probably doesnt like to shift already stuck, the wheels have to be moving together. you try it again after driving on the road or something?

Im wondering if the front diff solenoid isn't working. It could be the solenoid it'* self or it could be the wiring. The reason the stabile light came on is because it knows in 4wd it should see at least one of the front wheels spinning when the back wheel * are spinning.

have a update, I removed the 4x4 shift actuator in the front diff and tested it and it goes in and out when selecting the low/high range, put it back it and tested and dont hear it actually force it being locked in at the hubs
