The dash lights and dome lights no longer work on my 2007.5 3500. The fuse keeps blowing. I've tried to find the problem myself with no luck. I've also taken it to a place that only specializes in automotive electrical problems and they can't find it either. I've done multiple searches on different forums and haven't found anything that seems to relate. Has anyone had the same problem? Any ideas for where the short might be? Any help would be appreciated. This one has gotten pretty frustrating. Thanks for the help. :-)

 

I am not the brightest bulb in the box.
I would start where it all comes together. Light switch.
Then door switches. or vice versa.
