I had this problem a few years back.
I'm pretty sure the answer to your problem is a new stalk/switch unit - it was for me.
I don't remember it being very expensive or difficult to get one - I didn't have to wait. It's a very standard-Renault-looking unit made by Lucas so I would have thought it should be easy to get hold of one.
I think I went through a similar process that's been described here and I'd already ordered a new washer pump (which wasn't really the right one - it was different to what was in there, at least) took it all to bits and still nothing when I wanted screenwash but the wipers worked. In the end, I gave up but had it sorted very quickly at ARR at a very reasonable price.
