E-box Fan
Fuse 4 of the engine compartment fuse box (C0575) provides a feed to the E-box 
temperature sensor (C1258) on an NK wire. The temperature sensor is a thermostatic 
switch. When the temperature within the E-box reaches 35 °C (95 °F) the switch contact 
close. Current flows across the switch contacts (C1258) to the E-box fan (C0646) on an NK 
wire. The E-box fan (C0646) is earthed on a B wire.
When the temperature within the E-box drops to 27 °C (80...

HEATED REAR WINDOW (HRW)
DESCRIPTION
General
The HRW comprises eleven metallic strips bonded to the inside surface of the tail door glass 
to form an element. The metallic strips terminate in two larger strips at the bottom of the 
glass. Two connectors bonded to the terminations provide attachment of the supply and 
earth connections.
The HRW is controlled by the Central Control Unit (CCU) via a non latching switch mounted 
on the centre console. The switch...

DESCRIPTION AND OPERATION
FREELANDER 04MY 4.97
Fusible link 3 (C0571) is connected to the ignition switch (C0028) by an N wire. When the 
ignition switch is turned to the ignition position, current flows across the switch (C0028) to 
fuse 18 of the passenger compartment fuse box (C0588) on a G wire. Fuse 18 provides an 
ignition feed to the CCU (C0593).
When the CCU receives an ignition feed, it provides a feed to the HRW switch (C0072) on 
a GY wire. When the switch is pressed, current flows across the...

HEATED FRONT SCREEN (HFS)
DESCRIPTION
General
The Heated Front Screen (HFS) consists of two heater elements which are embedded into 
the LH and RH sides of the windscreen. Two connectors at the base of the windscreen 
provide the power feed and an integral earth for each of the heater elements.
Operation of the HFS is controlled by the CCU and a non latching switch on the centre 
console. The switch contains an LED which illuminates while the HFS is on. The...

HFS Switch
The CCU (C0429) monitors the condition of the HFS switch (C0131) by providing a feed on 
a KO wire. When the switch is pressed the CCU senses the momentary earth path, and 
(providing all other conditions are met) energises the HFS relay. The switch (C0131) is 
earthed on a B wire.
HFS Elements
The energised HFS relay (C0994) provides a feed to fuse A and fuse B (C1860) on a pair of 
NW wires. Fuse A (C1860) provides a feed to the LH screen...
