UX rear window heating malfunction

Hey there, I have a UX as well and had something similar happen last year. Was there any indication the battery was weak, like slow starts or anything? In my case, the rear defroster just stopped working out of the blue. Did you check the relevant fuses?

Thank you for your quick response. I did not observe any indications of a weak battery prior to this. Starting was always normal. I will check the fuses, but I am curious if replacing the battery resolved the problem for you?

Unfortunately, replacing the battery did not solve the problem. I ended up taking it to a workshop. They diagnosed it as a fault in the heating element itself after performing multiple tests. They ultimately replaced the rear window. I would suggest you have it professionally diagnosed to be sure.

I appreciate the information provided. It seems a workshop visit is indeed necessary. I will proceed accordingly. As a follow up, they have found the issue, and the cost for repair is 290€. Thank you again.
