The most common cause is dirty contacts in the switch. Pull off the covers
surrounding the steering column, and look into the right side of the switch
assembly as you pull back for the wash function, you will see the contacts
responsible for the connection. Clean them with a bit of super-fine
sandpaper, then wipe through a clean bit of paper or contact cleaner, and
that may fix the problem.
