Wipers are at the 'off' position but when I turn the car on the wipers start on their own, I have worked out that I can stop them if I turn an indicator on but as soon as I turn the indicator off, the wipers start up again. But after 15 minutes driving it stops and everything is Ok. I think it's something related to wiper relay and humidity. In Micra wiper relay is integrated in IPDM (intelligent power distribution module) which is under the left head light. I even opened the IPDM but I couldn't find any fuse or relay for wiper. Can anybody help me please?

Tracked it down to moisture in the screen washer pump. You can test if this is the cause for you by squirting the rear windscreen for a few seconds. If it stops the wipers then this is where the problem is. Remove the pump which just pulls out of tank (you do have to remove the front right headlight first, nightmare) take the pump out of the plastic housing and let it dry on a radiator overnight. I sealed mine on re-assembly with insulating tape to prevent damp getting in again.
