Just recently with no previous problems the other day I tried to engage the 4wd. Both 4H and 4L will not work also the light on the dash won't come on. Any idea or suggestions? This is a manual transmission, 4cyl.

 

J-shift or multimode tcase?

j-shift, either your add isn't working properly or your switch in your tcase isnt working, or your lights out in the dash

 

or the linkage is separated
