Rear Window Heater

Rear Window Heater
The rear window heater is supplied with power via relay 1 and relay 2 and is switched on by the rear window heater button. Relays 1 and 2 for the rear window heater pick up, thereby connecting the rear window heater to terminal 30. Relay 2 must have been enabled.
