Chevy 04 avalanche light went out on 4 wheel drive. I changed the fuses but they blew out. Dealer told me I needed actuator. Was put in light came back on but 4 wheel drive did not work. While driving, the vehicle was making noise. Took it to a mechanic, tech drove vehicle did not make any noise until tech put it in 4 wheel drive. The noise comes and goes while driving still.
