Dashboard lights

The other day the dash lights went out.
Check the fuse and it was blown. It is a 7.5 amp.

Changed the fuse and it blew right away.

So now what?

I don't think it is a bulb? Do I have to pull the dash out and tear everything apart?

Does anyone have a detailed wiring diagram for a 93 grand voyager?

thanks

Ok I pulled the dash apart last night.

I disconnected the insrument cluster, fuse still blew.

I disconnected the heating controlls, fuse still blew.

I disconnected the radio, fuse still blew.

I disconnected the panel about the heading controlls, fuse still blew.

I cut the orange wire that powers the lights in the panels and ran it to a +12 volt source and the lights light with no problems.

What is left?

I am almost postive the short is in the headlight switch.

Since everything else is jumped out and is working.

Does anyone have a headlight switch for sale cheap?
