No High Beams on my 2004 Grand Caravan
 

I don't have Highbeams on my caravan and no indicator light on the dash.... the switch in the steering column replaced with new...
from what understand there is no fuse or relay
What needs to be checked and how?
The whole fuse box was also replaced, and still with the same problem. It was used but I did try to clean the tabs on the front control module, did not try twisting them though
How do I follow the wires? Any color to look for?
Can I get a wiring diagram?

Does the low beams work and the 4 way/ turn signals flash?
