To be fair, I haven't picked this apart yet, but I was trying to reason out in advance where the problem is most likely to be, but I am confused.

When I activate the front wash/wipe the screen wipers go, but the washer motor and the headlamp wipers do not.

Looking at the wiring diagram, I can't explain this, but maybe someone here can!

P.S. Should the wipers stay running for a period after you release the wash switch?

Most likely cause is burnt contacts on the wiper stalk switch. The screen wipers are driven by a relay and only need a tiny current to initiate them but the headlight wipers and the washer motor are fed directly from the contacts.
