C5 Windshield Washer Heater Problem

Sounds familiar. Have you checked the cable and plug connection? Could be defective.

Where is the cable and plug connection for the windshield washer heater located? Easy to get to?

It's near the washer fluid reservoir, maybe behind some front trim. Honestly, a workshop could pinpoint the cause and repair it efficiently. Expect around 95€.

Thanks, I'll book it in with a workshop.
