Hey, new here. I have an 02 Dakota sport 4x4 4.7L. Today I tried switching it into 4wd, and there is nothing. No lights on the switch, and it won't engage. No noises, nothing. I looked for a fuse but couldn't find anything. Any idea where to look? Last week I was under the truck, had to fix a vacum line on the charcoal thingy to pass emissionsI didn't touch anything else.

 

do you have the electronic 4X4? iirc it is the switch that goes on them.

 

I don't know, how would I find out? I have the dial selector on the dash.

 

then u have the electronic one and as jonny said, it is the switch that goes on them more often than not, good luck fixing it and let us know how it goes

 

Thanks for the quick replys. Any ideas what the part costs? I'm guessing a dealer part, so I'm stuck till monday.

 

When mine did that I took it in under warranty and they said it was the transfer case control module - basically the motor that changes the gear for you. That part was iirc about $320. Not sure about the switch.
