No - the wipers are fully operational! HOWEVER - i did have a fiddle in the fuse box and managed to break one (which has remained out since) which killed the thermometer reading on the instrument cluster. But the fuse (when first checked) appeared ok. So i dont think replacement of the fuse will remedy the indicators but will sort out the thermometer....he says.Have your wipers also stopped working properly?
What is the overall function of the relay? Will give the hazards a go mate!I'm not sure about the location of the relay on the W124, on the W202 its in the boot next to the battery. It's green in colour (on the W202). Maybe disconnect the battery, take out the relay and clean the contacts and then reinstall?
You never did say if your hazards had stopped too.
