Do they work on manual? Fuse 17 in engine fusebox supplies wipers via a built in relay but its complicated as this relay switches to earth somehow activating the wipers.
Check for water ingress into the fusebox. Access the motor and wiggle the connecting plug with ign and wipers switched on. If no luck disconnect and re-connect, then check with a multimeter or test lamp check you have a switched live, a permanent live and an earth in the plug. After that its time to try a replacement motor there are probably loads on ebay.

 

Thanks wynb for the excellent response. :thumb:

They don't work on manual. There's no life in them at all.
I had a look for the relay but it's either not there or hidden behind a couple of green fuses.
No water that I can see in the fuse box.
Tryed wiggling and disconnecting the brown connector but still no joy.
I don't have a multimeter so I'll try a different motor, local scrapper has one.

 

You won't see the relay, its tiny and built into the fuseboard as its part of the CAN network. They can be replaced I think if you are handy with a soldering iron but I doubt that its at fault.

 

I got a wiper motor off eBay and just fitted it, still nothing.

Not sure what to do now

I bought a manual which has the electric schematics, no idea how to read them though

 

Seems to be working now, not sure what happened before :thumb:

 

Hello , I new here.
I have the same problem front wipers not working in any mode the water wash function is working though. Peugeot 607 2.2 Petrol year 2005.
I have disconnected the battery and will wait an hour and then try again

 

I fixed it, I changed the green 30 A fuse in the motor fuse box and now wipers working again. Dont know why the fuse was blown thoug but it was a very old fuse, maybe 20 years old.
