If the rear defroster in your Toyota Corolla is not functioning, I can assist you in determining the cause. One possible reason for the defroster not working is a blown fuse, which can prevent the defroster from receiving power when activated. Another potential cause could be corroded or damaged wiring connected to the defroster. I suggest checking the fuse initially; if it is intact, inspect the wiring for any issues and replace it if necessary.
Typically, when the rear defroster in your Toyota Corolla isn't functioning properly, the issue often lies with the wiring.
