Heated Glass Element: Description and Operation

The heated rear window relay supplies power to heated rear window grid. When the operator presses the heated rear window switch, the contacts inside the switch momentarily close and circuit C16 connects the relay timer to ground on circuit Z1. This causes the relay to change state and complete a circuit to energize the coil side of the relay and start the relay timer. Circuit G5 from fuse 9 in the fuse block supplies voltage to the coil side of the relay. Circuit Z1 provides ground for the relay.

When the heated rear window relay energizes, the contacts inside the relay close and connect circuit F32 to circuit C15. Fuse 3 in the fuse block protects circuit F32.

Circuit C15 is double crimped at the heated rear window relay. One branch of circuit C15 powers the indicator lamp in the heated rear window switch. The other branch of circuit C15 powers the heated rear window grid. Circuit Z1 provides ground for the heated rear window grid.

At the rear window grid, circuits C15 and Z1 pass through lift gate support struts.
