Camaro rear window heating malfunction

My 2017 Chevrolet Camaro with a gasoline engine has a rear window heating malfunction. The car has 191034 km. Diagnostic scans show a stored error. Also, the windshield heating isn't working as well as it should. Any ideas?

A 2017 Chevrolet Camaro experienced a rear window heating malfunction, with diagnostic scans showing a stored error. The windshield heating was also underperforming. The issue was traced to a weak battery, which can cause isolated electrical problems by prioritizing power to essential systems. Replacing the battery resolved the heating issues.

Could be the battery. Have you checked its voltage and overall health? A weak or bad battery can cause electrical issues like that. Does the car struggle to start, especially when it's cold?

Thanks, I haven't checked the battery voltage under load specifically, but I will. Could a weak battery really only affect the rear window and windshield heating when other electrical systems seem fine?

A weak battery can cause seemingly isolated issues because the car's electrical system prioritizes power. The heating elements draw a lot of current. If the battery is weak, the car might cut power to those systems first. If the battery is good, you might need a workshop to diagnose it properly.

Thanks for your help. The battery was the problem. Replacing it fixed the rear window heating. Repair cost was 290€.
