Peugeot 308 rear window heating issue

Interesting. I've got a 308 too, and I had similar issues with the defroster last winter. The rear defroster was completely dead, and the auto defrost function seemed off. Did you check your battery voltage? A weak battery can cause all sorts of weird electrical problems in these cars.

Thanks for the quick reply! I haven't checked the battery voltage myself, I don't have the right tools. I was hoping it was just a fuse, but no luck there. Did checking the voltage solve your rear window heater issue?

No, checking the voltage didn't solve it immediately, but it confirmed the battery was on its way out. Eventually, I had to replace the battery. It might be worth getting it checked professionally, as the rear defroster issue could be linked. I ended up paying around 290€ at the workshop.

Okay, that's really helpful. I appreciate you sharing your experience! I'll take it to a workshop and have the battery checked and everything, I'll let you know what happens.
