I just recently picked up and 08 Sierra LMM, but I’m having trouble with my 4x4. The indicator takes a while to say its in 4x4, but it engages the transfer case just fine and spins the front drive shaft. I also replaced the actuator on the front differential, but it’s still not working, and I believe the actuator isn’t getting any power. Any ideas?
