Head lights acting weird 97 civic

So my head lights have been acting weird.
So when my light are just running regular
my driver side light is out and foggers
won't turn on. If I turn my brights on my
driver side turns on and my foggers, but
the light on my dash for my bright doesn't
turn on. I understand that my regular lights
and brights are different so I switch my  
passenger light with my driver side light
and the light from the driver side worked
on both regular and my brights. I checked
my fuse and they look fine but I just
realized that some are missing. Which I
thought was weird. But I also have a
aftermarket head unit and I think it has bee
causing issues because I believe it blew
the bulbs on my dash and AC lights. If
anyone knows what to do to fix it then that
would be great!
