If heating still does not work, check the control unit comfort electric equipment. If conductors of a heater are torn, it is possible to use a usual current-carrying varnish for repair. For this purpose clear the damaged place a thinner or ethylene. Paste over the damaged place from both parties with a gluing tape and put with a small brush a current-carrying varnish.
