It is probably the wiper pulse board. Go to you local parts store to buy it and it is just unplug the wire harness to it and three torx screws to replace it. Let me know how it goes.

I did a new wiper pulse board, it worked for a few minutes than would not shut off again. The pulse board I have has only one screw in the middle.

Ok so the pulse board should be good then. It can't be the wiper motor because it would then quite instead so the only left possibility is the combonation switch or multi function switch.

Thanks I will try the combination switch, because I didn't think it would be the motor either. I will let you know the outcome.
