The 4wd selector switch on my 2005 Dodge 3500 stays on 2wd. If I select 4 hi or 4 lo nothing happens. No dash lights and I don't hear the actuator engaging. I have checked the fuses. I changed the switch but it did not change the behavior. Can anyone tell me what I might check? Thank you.

 

Having the same problem with my 06 1500 right now. Have you been able to fix it yet? I’ve changed the switch and the transfer case motor- still nothing.
