When the headlight switch melts, do the dash lights work or not?

While driving last weekend, w/ brights on, everything was copasetic 'til we
stopped to buy groceries (after about a 4 hr drive).  Got back in the van
and the headlights wouldn't work, except by holding the brights on.  I know
this has been mentioned, but no one has mentioned dash lights.  If typically
the dash lights do not work, I guess I need to look elsewhere for the problem.

Thanks...
