Where is fuse box on 1990 Pontiac Firebird

I am having problems with the power windows and sound to the speakers . Looking to see if there are fuses to repair both these problems.

It's a good idea to get a repair manual if your going to work on your own vehicle, and it will include the wiring diagram necessary to diagnose electrical issue like this. Try and you can have one in minutes, for less than $30.00.
