4x4 gremlin

Hello. 4x4 lights don't illuminate when I turn the truck on. They don't illuminate when I turn the round dial. I don't feel or hear anything engage when I turn the dial. I've checked the 30amp fuse #20 and it's fine too. The first time I turned the truck on last week when I first got it I did see the light turn on when I turned the dial. Now it doesn't. Thx these are all the codes I have left. Thanks

Here's the online link to the service manual if you don't have it already.
You can peruse through and find the wiring diagrams and control modules, etc...
The 4x4 control module is in the pillar right by the driver's hip area.
