Peugeot 508 Headlight Washer Problem

I had a similar issue on my 508. Does it also have LED headlights? If so, the headlight washer pump might be the culprit. They're known to fail, sometimes causing a leak that affects the windshield washer system as well.

Yes, mine does have LED headlights. A leak makes sense, I did notice a bit of a puddle under the front. Is it difficult to access the pump to check the cable connection?

Accessing it can be a pain without the right tools. Given the puddle, and you've already checked the fuses, it's likely a faulty pump or a wiring issue. I'd recommend getting it checked out by a workshop; diagnosing electrical issues without proper equipment can be tricky and potentially damage other components.

Thanks for the advice. I took it to a workshop, and you were spot on. It was indeed the headlight washer pump and its corroded cable connection. The repair cost me 165€. Now everything is working again!
