Kubistar Windshield Washer Heater Fault

I had similar freezing issues with my Nissan Micra. Is your washer fluid reservoir also emptying faster than normal? Have you checked the fuse box? It might be the issue with the windshield heater.

Reservoir level seems normal. But is the fuse box easily accessible? Where exactly should I be looking?

If the reservoir level is normal, then the problem is probably as you suspected. Replacing the fuse is easy enough, but the error memory issue suggests a deeper fault. Is it worth fiddling around with a multimeter in freezing weather, or should you just take it to a workshop?

Thanks for the help. I took it to a shop, and you were right. The cable to the windshield washer heater was defective and the fuse was gone. Cost 95€ to fix.
