93 Caravan fusebox/stereo?

Hi, Everyone!

Thanks for the great help I've gotten from these boards!

I'm hoping there is a cheap fix for my stereo not turning
on--- found the fusebox but don't have an index as to
which fuse is for the stereo/ which fuse is for what.
Someone suggested checking the fuse first and that's
the step I'm stuck on.

I know, I know, a map would be in my owner's manual...
buuuut...

Knob still "clicks" when I turn the radio off/on, but
no volume... ohh, I so pray I don't have to rip the
dash out to replace the switch!

Any cluse which fuses are for what in the 93 era Caravans?

Thx!!!
