AMBIENT TEMP SENSOR
REMOVAL
The ambient air temperature sensor is located on
the inside of the right front bumper beam (Fig. 11).
This sensor will inform the ATC system of the ambi-
ent temperature outside the vehicle. This sensor is
used by the ATC system to adjust blower speed, tem-
perature offsets, evaporator temperatures and mode
control.
(1) Remove sensor mounting screw.
(2) Disconnect sensor wiring connector.
INSTALLATION
(1) Connect the sensor wiring harness connector.
(2) Install the sensor fastener screw and tighten to

POWER MODULE
DESCRIPTION
The blower motor power module is only used in
vehicles equipped with Automatic Temperature Con-
trol (ATC). It is located on the lower right side of the
HVAC unit housing, and is controlled by the Body
Control Module (BCM).
OPERATION
The power module receives pulse width modulated
(PWM) signals from the BCM. The power module
varies voltage to the blower motor for different
blower speeds based on the ATC software. There are
14 selectable speeds, while the Auto mode provides
256 variations.
