Help- 4 wheel drive question 92 k1500 4x4
 

The lights on my floor display for the
Two front wheels is not coming on
Anymore & it is not engaging my front
Wheels In 4 wheel drive.
It worked last time I used it, & I've
Done no off road activity sense, there's
Really no reason for it not to be
working.
I check the 4x4 fuse in the fuse panel
Its not blown.. Wires underneith going
To my transfer case & front diff but
Everything seem to be where it should be.
Is there other fuses or connections I
Could check? My Haynes manual is not
Covering any of this. What could be a
Possible fix..?
