To prevent the battery from being discharged by a heating element left on when the engine is not running, the heating can only be turned on when the ignition is on. To do this, power is supplied to the heated rear window switch through an additional relay (ignition relay) K4, triggered when the ignition is turned on.
The rear window heating element is powered by fuse F15, which is directly connected to the power sources.
If the rear window is not heated when the rear window is turned on, check the F15 fuse, the wires and their connections, as well as the K10 switch and relay.
Mounting block: K1 - a place for installing a headlight washer relay; K2 - relay for switching on the power window circuit; KZ - starter enable relay; K4 - additional relay (ignition relay); K5 - relay for turning on direction indicators and alarms; K6 - relay for turning on the washer and windshield wiper; K7 - high beam headlight relay; K8 - relay for turning on the sound signal; K9 - relay for turning on the front fog lights; K10 - relay for turning on the heating of the rear window; K11 - relay for switching on the front seat heating circuit; K12 - a place for a backup relay; F1-F32 - fuses (circuits protected by pin-type fuses are shown in Table. 9.3)
