RADIATOR FAN RELAY
DESCRIPTION
The radiator fan relay is a solid state type and is
located on the front bumper reinforcment (Fig. 22).
Refer to WIRING DIAGRAMS for a circuit sche-
matic.
OPERATION
The solid state radiator fan relay is controlled by
the Powertrain Control Module (PCM) by way of a
Pulse Width Modulated (PWM) signal. The relay con-
trol circuit supplies a 12 volt signal to the PCM. The
PCM then pulses the ground circuit to achieve fan on
time. The relay provides a voltage to the fan motors
which is proportional to the pulse width it receives
from the PCM. The duty cycle ranges from 30% for
low speed operation, then ramps-up to 100% for high
speed operation. This fan control system provides
infinitely variable fan speeds, allowing for improved
fan noise, A/C performance, better engine cooling,
and additional vehicle power.
To control operation of the relay, the PCM looks at
inputs from:
²Engine coolant temperature
²A/C pressure transducer
²Ambient temperature from the body controller
²Vehicle speed
²Transmission oil temperature
The PCM uses these inputs to determine when the
fan should operate and at what speed. For further
information on fan operation, (Refer to 7 - COOL-
ING/ENGINE/RADIATOR FAN - OPERATION).
REMOVAL
(1) Open hood.
(2) Disconnect and isolate the battery negative
cable.
(3) Remove the radiator crossmember to front fas-
cia closure panel.
(4) Disconnect the relay electrical connector (Fig.
22).
(5) Remove the rivet attaching the relay to the
front bumper beam (Fig. 22).
(6) Remove the relay.
INSTALLATION
CAUTION: The relay mounting location is designed
to dissipate heat. Ensure the relay is securely
attached to prevent relay ªthermalº shutdown and
relay damage, resulting in possible engine over-
heating.
(1) Position relay and install a new rivet (Fig. 22).
(2) Connect electrical connector to relay.

an available option. Several combinations of radio
receivers are offered on this model. The audio/video
system uses an ignition switched source of battery
current so that the system will only operate when
the ignition switch is in the RUN or ACCESSORY/
ACCESSORY DELAY positions.
The audio system includes the following compo-
nents:
²Antenna
²CD changer (if equipped)
²DVD player (if equipped)²Radio noise suppression components
²Radio receiver
²Speakers
²Video screen (if equipped)
Certain functions and features of the audio/video
system rely upon resources shared with other elec-
tronic modules in the vehicle over the Programmable
Communication Interface (PCI) bus network. The
data bus network allows the sharing of sensor infor-
mation. For diagnosis of these electronic modules or
of the data bus network, the use of a DRB IIItscan
tool and the proper Diagnostic Procedures manual
are recommended.
