If so, is the problem in the switch, or some other part? Just prior to this, the wiper was stopping randomly while on intermittent setting. I thought I read on here that this was cured by cleaning a contact somewhere?

More then likely the combi switch has given up..  Fairly common.

Not sure how you would get into the switch to clean the contact..never 
attempted to take one apart.

I would recommend taking the wiper mechanism off and cleaning/lubing the 
internals..  the OE grease turns to a pretty solid goo with time and 
kills the wiper motor.
