27.22. Heater of back glass

The heater of back glass works only after turn of a key in the ignition lock in situation 1 or 2. At inclusion of a heater of back glass the control light-emitting diode on the switch button lights up.

The heater of back glass consumes very big current therefore include it for a while, necessary only for elimination of fogging of back glass. The heater of back glass will automatically be disconnected in 15 minutes of work.

At inclusion of several powerful consumers of the electric power and low capacity of the accumulator the heater of back glass is automatically disconnected and in this case the control light-emitting diode blinks. At increase in tension in onboard network of the car the heater of back glass automatically joins.
