The heated seats of the Toyota Camry are heating up too much or weakly

The algorithm of heating the seats on the Toyota Camry VII is still unknown, and the reasons why it warts too much or too little. The heat may, for example, be turned on for 3 minutes and then switched off without heating the seats. There are also cases where, on the contrary, the heating of seats burned through the cloth. Official dealers still do not admit this case.
