I have no dash lights or dim headlights. Everything else works fine.

What is your question?

Everything else works my taillights, brake lights, tag lights turn signal inside lights park lights. I just don't have dash lights and my headlight won't work on dim just on bright. So I know its not my fuse. What else could it be? I know I have juice going up to my dimmer switch but don't know how to test my dimmer switch itself. Thanks in advance.
