It's only started the last few days.

Randomly, the wipers come on for a single wipe. So on a dry windscreen, very annoying!

It might happen 4 times in a 30 minute trip. Sometimes soon after the last time, sometimes with a long break in between.

Anyone had this problem before?

I've done some searching, and i think i need to investigate some relay, and possibly the wiper stalk.
anybody offer some guidance?

Cheers
