wipers work ok for a short while then just stop,if you move the switch leaver they will work again for a short while,could the fault be the relay or somethingelse?

Could the fault be the relay? Yes
Or something else? Yes

Could be the switch itself.

I had this fault on a VW Golf - the wiper motor bolts had vibrated lose and the motor was wobbling - eventually the linkage would jamb up and the wipers stop - then - when I switched off - the tension in the linkage would relax and it would all start going again when I switched on.

Eventually it all stopped working completely.

Check out the linkage..., March 2015
