H1 Windshield Washer Heater Issue
Summary of the thread
The windshield washer heater in a 2018 Hyundai H1 diesel is malfunctioning, causing the spray nozzles to freeze in cold temperatures. The error memory indicates a problem, and a defective cable or plug is suspected as the cause. After consulting a workshop, it was confirmed that a defective cable was indeed the issue, and it was repaired.

I haven't checked the voltage. Where is the heater connector located? I'm not sure I can find it.

If you're unsure, I'd suggest a workshop. It's likely the cable or plug, but without the right tools or knowledge, it could get worse.

Thanks for the advice. I took it to a workshop. The repair was 95€. It was a defective cable, as suspected.

That's strange. Maybe a fuse? Have you checked the voltage at the heater connector when the washer is on? Is there any voltage there?
