Seat Toledo Washer System Problem
Summary of the thread
A 2016 Seat Toledo with high mileage experienced issues with both the headlight cleaning and windshield washer systems. The suspected causes included a defective cable connection to the pump or a faulty relay. Another owner suggested that a failed headlight washer pump could affect the windshield washer, as they are interconnected. The problem was resolved by inspecting and repairing the connections and clearing a clog in the hose, restoring full functionality.

That is interesting. I had not considered that the headlight cleaning system could impact the windshield washer. Could you please elaborate on how you diagnosed the headlight cleaning system pump as the source of the problem?

Certainly. In my case, the windshield washer stopped working at the same time. If the headlight washer pump fails, it can indeed affect the windshield washer. The best course of action might be to have a workshop inspect the relevant connections, as that sorted my problem.

Thank you for the information. I took it to a workshop, and you were spot on. The mechanic confirmed a defective connection to the pump, and also found a clog in the hose, probably due to prolonged malfunction. The final cost was 165€, including parts and labor. Everything is working perfectly now.

I also own a Toledo and experienced a very similar issue. The windshield washer stopped working entirely. Have you checked the headlight cleaning system pump? It might be the culprit, as they are often interconnected.
