hi Guys,
Quick bit of info if you find your windscreen wiper failing mid swipe. I was told I was going to need a new motor, as all seemed fine with the fuses etc. When the AA turned up he discovered it was the earth wire making a poor connection (this might also cause an intermittent fault to). Apparently the motor is rubber mounted and where the earth makes contacts just gets dirty etc and eventually fails. It was fixed by attaching a new earth wire from the motor to the body of the car. Once attached it fired up first time.
Unfortunately people can be advised they need a new motor and in the process of fitting a new one the earth connection is reestablished but it falsely appears to be the change of motor that has solved the problem.
hope this helps
Sarah
