HEATED REAR WINDOW
HEATED REAR WINDOW
The heated rear window relay supplies power to
heated rear window grid. Circuit F83 from fuse 8 in
the fuse 8 in the fuse block supplies power to the
heated rear window relay when the ignition switch is
in the ACCESSORY or RUN positions.
When the operator depresses the heated rear win-
dow switch, the contacts inside the switch momen-
tarily close and circuit C80 connects the switch to the
relay. This causes the relay to change state and com-
plete a circuit to energize the coil side of the relay
and start the relay timer.
Circuit F81 from fuse 18 in the fuse block supplies
voltage to the coil and contact sides of the relay. Cir-
cuit Z1 provides ground for the relay.
When the heated rear window relay energizes, the
contacts inside the relay close and connect circuit
F81 to circuit C15. Circuit C15 splices to the power
the heated rear window grid and the indicator lamp
in the heated rear window switch. Circuit Z1 pro-
vides ground for the heated rear window grid.

HOW TO USE THIS GROUP
The purpose of this group is to show the electrical
circuits in a clear, simple fashion and to make trou-
bleshooting easier. Components that work together
are shown together. All electrical components used in
a specific system are shown on one diagram. The feed
for a system is shown at the top of the page. All
wires, connectors, splices, and components are shown
in the flow of current to the bottom of the page. Wir-
ing which is not part of the circuit represented is ref-
erenced to another page/section, where the complete
circuit is shown. In addition, all switches, compo-
nents, and modules are shown in theat rest posi-
tion with the doors closed and the key removed
from the ignition.
If a component is part of several different circuits,
it is shown in the diagram for each. For example, the
headlamp switch is the main part of the exterior
lighting, but it also affects the interior lighting and
the chime warning system.
It is important to realize that no attempt is
made on the diagrams to represent components
and wiring as they appear on the vehicle. For
example, a short piece of wire is treated the
same as a long one. In addition, switches and
other components are shown as simply as pos-
sible, with regard to function only.
The wiring diagram show circuits for all wheel-
bases. If there is a difference in systems or compo-
nents between wheel-bases, an identifier is placed
next to the component.
SECTION IDENTIFICATION
Sections in Group 8W are organized by sub-sys-
tems. The sections contain circuit operation descrip-
tions, helpful information, and system diagrams. The
