Ok, I have not been able to use 4wd for quite some time now, I checked the vaccum line under the battery and it was not connected, I hooked it back up thinking it would solve the poblem but it's obviously something else because it still doesnt work.... So now my question is, Where do I start with touble shooting??

Thanks

 

Start with the search function! LOL There are MANY topics on INOP 4wd.
