Going by Spiderserie4's post I had a look at the column stalk and bingo! A soldered wire is loose (the blue on in the pic - should be attached like the purple one with the black plastic cover) and it's actually this one that makes intermittent/park work!
Now all I have to do is to get it fixed. In the mean time I've re-installed the wipers motor and put the cowl / wipers back, complete with the new water nozzles! :-)
