fuse or relay

I have a 1993 camry and the power windows, powerlocks, power seats, and sunroof all stopped working. I suspect it is a fuse but does anyone know where I might locate the right one?

E-mail me I have the wiring diagram in PDF Format.

If it's not the fuse,look under the dash (near the firewall by the left kick panel) for a bank of resettable circuit breakers.

It is most likely a fuse if more than one thing is completely inoperable at once.
