S40 haunted wipers!!
Hi there Volvo folk,
I'm new to Volvos. Really like my '04 S40 2.4 which I got last year. The only niggle is the (seemingly common-ish) problem with the wipers randomly coming on! I've trawled the forum and have had the ECM (?) unit out for cleaning. This didn't work, so I've done the same with the fuse box under the bonnet. No joy. Perhaps the connections to the motor are corroded. However, I can't seem to get to it though, as the windscreen cowl won't budge. Any help gratefully received |

do you have the auto wipers option which automatically come on when there is even a little drop of rain? maybe check the sensor for that?

Yes, I do have that option I think. I haven't used it, as far as I know though.. Do you know where the sensor is located by any chance? |

Rain sensor is top center of the windscreen... but auto-wipers are off when you start up until you turn them on... you see the little wiper/raindrop icon in the bottom LED above the mileage

When the wipers come on by themselves, I try switching the 'auto' function on/off but the icon never lights up. Not sure if that proves anything though! Is the sensor in the module that has the rear-view mirror attached? Does it have it's own fuse? |

Well, it's not the sensor.
The wipers came on again of their own accord. I found the sensor and disconnected it. The wipers kept going... |
