GrandlandX Headlight Washer Failure

Sounds familiar! Had the exact same thing with my old Peugeot 308. Washer stopped working completely, and it turned out to be a dodgy cable connection to the pump. Have you checked the fuses and relays?

You mention a cable connection. Could you elaborate on the location and accessibility of this connection? I want to inspect it before taking it in.

Yeah, on the Peugeot it was near the bottom of the washer fluid tank, pretty awkward to get to without ramps. If the fuses are okay, honestly, save yourself the hassle and get a workshop to check it out. Probably a defective cable or pump.

Took it to a workshop as you suggested. The cable connection of the pump was indeed defective. Repair cost 165€ . Thanks!
