CT200h Rear Window Heating Failure

I have a CT200h and had something similar happen last winter. Did you check the fuses? It might be a simple fix before diving into battery diagnostics.

Thank you for your suggestion. I have already inspected the relevant fuses; they appear to be intact. Was your issue resolved by replacing a fuse, or did further intervention become necessary?

Nah, fuses were fine for me too. I'd get it checked out by a shop. They ran some tests and found a deeper problem in the electrical system. Probably best to avoid messing with it yourself.

Understood. I appreciate the confirmation that the problem extends beyond a simple fuse replacement. The vehicle has been assessed, and the repair, costing 290€, will proceed, targeting the faulty battery as the likely cause. Thank you for your input.
