[Sneakysilver]

Well a few days ago I had serv 4wd pop up and so I went through 4hi and 4lo both engaged tc still goes into N but my locker will not the light flashes forward ten seconds then stops. A shop said something about an actuator failure maybe in the rear? Havnt done much research due to the holidays but drives fine has 110k on it oil changed 40 miles ago

Check the wiring to the locker. If I am not mistaken, if the correct resistance isn't seen across the wires it will trigger the Serv 4WD message.

x2, had that happen a month ago, I just cut out the quick disconnect then re-soldered the wires back up and problem solved... Took like 10 min tops
