Abstract

A wiper rest heater is connected to a sensor. The sensor, when temperatures are low, directly or indirectly measures whether or not the windshield wiper can be moved when the wiper motor is switched on, without thereby damaging the wiper blade element or the motor. As a function of this, the wiper rest heater is then either switched on or off by an intelligent control.
