Richard,
Don't pull your dash. This will likely cause more problems than what you
now have.
You must have power at the green wire on the wiper switch. If Fuse #8 is
good, and you have no power at the wiper switch and you have no power at the
green wire on the washer switch, the most likely cause is the green wire
connection at Fuse #8. Wire itself is seldom the problem. Connections are
normally the problem. Connections corrode over time or get pulled loose while
working on some unrelated problem.
If the green wire connection at the fuse is good (and you have power at the
fuse) and you have no power at the washer or wiper switch, I would
recommend installing a new wire from Fuse #8 to the wiper washer switches. This
can be done much, much easier than pulling the dash. Use a unique color so
you will remember why that wire is there. Put the wire in temporarily so you
can test that it will fix the problem.
Be very, very careful when installing or removing wires from the switches.
The terminals on the switches are easily broken and this will produce,
believe me, a profound sinking feeling.
BTW an easy way to remove and install the wiper and washer switches is
described, with pictures, at:

Let me know what you find.
The main thing is to keep the main thing the main thing.
Do the best you can with what your have where you are.
Have fun today!

My wipers and washer don't work. I checked the diagram and it looks to me
like the Green wire at the wiper switch is supposed to be hot. Even with
the key on, there's no power to any of the wires at the switch. I crawled
underneath the dash and tried tracing the green wire, moving things
around, and blew the #8 fuse.
I'm far from an electrical guy, but it looks to me like I have a short
somewhere in the loom under the dash which will have to come off.
Any ideas?
