Citroen C4 Wiper Failure

Sounds frustrating! I had a similar issue with my old Renault Megane, although it wasn't exactly the same. The wipers would work intermittently, and sometimes not at all. Does the turn signal, cruise control or the rain sensor work?

The turn signals seem fine, and so does the cruise control. I don't have a rain sensor, unfortunately. Where was the issue in your Megane, exactly? Was it the wiring harness?

Yeah, in the end, it turned out to be a corroded connector in the wiper motor wiring. I'd check the connections and wiring really carefully before diving in too deep. If you're not comfortable poking around with electrics, it might be worth just taking it to a workshop.

Thanks a lot for the advice! I took it to the workshop today, and you were spot on! It was indeed a corroded connector in the wiring harness, as well as a defective plug connection. They cleaned it up and replaced the connector. Cost me 95€, but at least it's sorted! Cheers!
