Hey... I'm new here and have a question. I've been trying to engage my 4 wheel drive and it isn't working I check both sets of fuse's and it still ain't working. The light doesn't come on or anything. There is no grinding noise coming from Tue xfer case and it has automatic locking hubs. Please help.

 

switch/motor might be bad

 

How do I check to see if the switch is bad number one. And where is the motor located and is it a dealer part or can I g3t it from a standard store.
