Sedici Rear Window Heating Issue

Rear window heating on my 2009 Fiat Sedici (gasoline engine) isn't working. Error memory registered a fault, and the windshield heating seems weak too. Could a discharged battery cause this?

The rear window heating issue on a 2009 Fiat Sedici was linked to a fault in the error memory and weak windshield heating. A discharged or defective battery was identified as a potential cause of these electrical issues.

Possibly. A weak battery can cause electrical issues. Have you checked the battery's voltage? Have you done defroster repair before? Could be a fuse, but modern systems are sensitive to low voltage.

I haven't checked the voltage, and I've never done defroster repair. Can I check the voltage myself, or should I take it to a professional?

If you're not comfortable with electrical testing, a workshop is best. Given the error code and weak windshield heating, it's likely more than a fuse. A defective battery fits the symptoms. Expect around 290€ repair costs.

Thanks! Took it to a shop, and you were right – it was a bad battery. Sorted now, with a new heating coil!
