BLEND DOOR ACTUATOR
DESCRIPTION
The blend door actuator is a reversible, 12-volt
Direct Current (DC), servo motor (Fig. 3). The single
blend door actuator is located on the outboard side of
the rear heater-A/C unit housing, below the mode
door actuator. The blend door actuator is mechani-
cally connected to the blend air door. The blend dooractuator is interchangeable with the actuator for the
mode door. Each actuator is contained within an
identical black molded plastic housing with an inte-
gral wire connector receptacle. Two integral mount-
ing tabs allow the actuator to be secured with two
screws to the rear heater-A/C unit housing. Each
actuator also has an identical output shaft with
splines that connects it to the pivot or linkage of the
proper door. The blend door actuator does not require
mechanical indexing to the blend air door pivot, as it
is electronically calibrated by the front heater-A/C
control module. The blend door actuator cannot be
adjusted or repaired and, if damaged or faulty, it
must be replaced.OPERATION
The blend door actuator is connected to the front
heater-A/C control module through the vehicle elec-
trical system by a dedicated two-wire take out and
connector of the rear HVAC wire harness. The blend

door actuator can move the blend air door in two
directions. When the front heater-A/C control module
pulls the voltage on one side of the motor connection
high and the other connection low, the blend air door
will move in one direction. When the module reverses
the polarity of the voltage to the motor, the blend air
door moves in the opposite direction. When the mod-
ule makes the voltage to both connections high or
both connections low, the blend air door stops and
will not move. These same motor connections also
provide a feedback signal to the front heater-A/C con-
trol module. This feedback signal allows the module
to monitor the operation and relative positions of the
blend door actuator and the blend air door. The front
heater-A/C control module learns the blend air door
stop positions during the calibration procedure and
will store a Diagnostic Trouble Code (DTC) for any
problems it detects in the blend door actuator cir-
cuits. A DTC can be retrieved and the blend door
actuator can be diagnosed using a DRBIIItscan tool.
Refer to the appropriate diagnostic information.

DESCRIPTION
TERMINAL LEGEND
NUMBER IDENTIFICATION
30 COMMON FEED
85 COIL GROUND
86 COIL BATTERY
87 NORMALLY OPEN
87A NORMALLY CLOSED
The blower motor relay (Fig. 5) is a International
Standards Organization (ISO) mini-relay. Relays con-
forming to the ISO specifications have common phys-ical dimensions, current capacities, terminal
patterns, and terminal functions. The ISO mini-relay
terminal functions are the same as a conventional
ISO relay. However, the ISO mini-relay terminal pat-
tern (or footprint) is different, the current capacity is
lower, and the physical dimensions are smaller than
those of the conventional ISO relay. The blower
motor relay is located in the Intelligent Power Mod-
ule (IPM), which is in the engine compartment near
the battery. See the fuse and relay layout map
molded into the inner surface of the IPM cover for
compressor clutch relay identification and location.
The black, molded plastic case is the most visible
component of the blower motor relay. Five male
spade-type terminals extend from the bottom of the
base to connect the relay to the vehicle electrical sys-
tem, and the ISO designation for each terminal is
molded into the base adjacent to each terminal. The
ISO terminal designations are as follows:
²30 (Common Feed)- This terminal is con-
nected to the movable contact point of the relay.
²85 (Coil Ground)- This terminal is connected
to the ground feed side of the relay control coil.
²86 (Coil Battery)- This terminal is connected
to the battery feed side of the relay control coil.
²87 (Normally Open)- This terminal is con-
nected to the normally open fixed contact point of the
relay.
²87A (Normally Closed)- This terminal is con-
nected to the normally closed fixed contact point of
the relay.
The factory-installed blower motor relay cannot be
adjusted or repaired. If the relay is damaged or
faulty, it must be replaced.
OPERATION
The blower motor relay is an electromechanical
switch that uses a low current input from the Front
Control Module (FCM) to control the high current
output to the blower motor resistor (manual heater-
A/C control) or blower power module (automatic heat-
er-A/C control). The movable common feed contact
point is held against the fixed normally closed con-
tact point by spring pressure. When the relay coil is
energized, an electromagnetic field is produced by the
coil windings. This electromagnetic field draws the
movable relay contact point away from the fixed nor-
mally closed contact point, and holds it against the
fixed normally open contact point. When the relay
coil is de-energized, spring pressure returns the mov-
able contact point back against the fixed normally
closed contact point. The resistor or diode is con-
nected in parallel with the relay coil in the relay, and
helps to dissipate voltage spikes and electromagnetic
interference that can be generated as the electromag-
netic field of the relay coil collapses.

BLOWER MOTOR RESISTOR
DESCRIPTION
A blower motor resistor is used on this model when
it is equipped with the manual heater-A/C control
(Fig. 7). Models equipped with the optional Auto-
matic Temperature Control (ATC) use a blower power
module, instead of the blower motor resistor. The
blower motor resistor is installed in a mounting hole
on the back of the rear heater-A/C unit housing,
directly above the expansion valve. The resistor con-
sists of a molded plastic mounting plate with an inte-
gral connector receptacle. Concealed behind the
mounting plate within the rear heater-A/C unit hous-
ing are two coiled resistor wires contained within a
protective stamped steel cage. The resistor mounting
plate is secured with two screws to the rear heater-
A/C unit housing and is accessed for service by
removing the right quarter and D-pillar trim panels.The blower motor resistor wires will get hot when
in use. Do not touch the resistor wires or the protec-
tive cage if the blower motor has been running. The
blower motor resistor cannot be adjusted or repaired
and, if faulty or damaged, it must be replaced.
OPERATION
The blower motor resistor is connected to the vehi-
cle electrical system through a dedicated take out
and connector of the rear HVAC wire harness. The
blower motor resistor has two resistor wires, each of
which will reduce the current flow through the
blower motor to change the blower motor speed. The
blower motor switch in the manual heater-A/C con-
trol directs the ground path for the blower motor
through the correct resistor wire to obtain the
selected speed. With the blower motor switch in the
lowest speed position, the ground path for the motor
is applied through both resistor wires. Each higher
speed selected with the blower motor switch applies
the blower motor ground path through fewer of the
resistor wires, increasing the blower motor speed.
When the blower motor switch is in the highest
speed position, the blower motor resistor wires are
bypassed and the blower motor receives a direct path
to ground through the blower motor switch. The
blower motor resistor may be diagnosed using con-
ventional diagnostic tools and methods.
DIAGNOSIS AND TESTING - BLOWER MOTOR
RESISTOR
Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
(1) Disconnect and isolate the battery negative
cable.
(2) Disconnect the rear HVAC wire harness con-
nector for the blower motor resistor from the resistor
connector receptacle.
(3) Check for continuity between each of the
blower motor switch input terminals of the blower
motor resistor and the resistor output terminal. In
each case there should be continuity. If OK, repair
the wire harness circuits between the blower motor
switch and the blower motor resistor or the blower
motor pigtail wires as required. If not OK, replace
the faulty blower motor resistor.Fig. 7 Blower Motor Resistor

equipped with the optional Automatic Temperature
Control (ATC) heating and air conditioning system
(Fig. 9). The solenoid is located on the inboard side of
the rear expansion valve where it is concealed by the
quarter inner trim panel behind the right rear wheel
house. A short two-wire pigtail harness connects the
solenoid to the vehicle electrical system through a
take out and connector of the rear HVAC wire har-
ness. The solenoid is integral to the rear expansion
valve. The rear expansion valve solenoid cannot be

The mode door actuator is a reversible, 12-volt
Direct Current (DC), servo motor (Fig. 10). The sin-
gle mode door actuator is located on the outboard
side of the rear heater-A/C unit housing, above the
blend door actuator. The mode door actuator is
mechanically connected to the mode door linkage.
The mode door actuator is interchangeable with the
actuator for the blend air door. Each actuator is con-
tained within an identical black molded plastic hous-
ing with an integral wire connector receptacle. Two
integral mounting tabs allow the actuator to be
secured with two screws to the rear heater-A/C unit

cannot be adjusted or repaired and, if damaged or
faulty, it must be replaced.
OPERATION
The mode door actuator is connected to the front
heater-A/C control module through the vehicle elec-
trical system by a dedicated two-wire take out and
connector of the rear HVAC wire harness. The mode
door actuator can move the mode door in two direc-
tions. When the controlling heater-A/C control mod-
ule pulls the voltage on one side of the motor
connection high and the other connection low, the
mode door will move in one direction. When the mod-
ule reverses the polarity of the voltage to the motor,
the mode door moves in the opposite direction. When
the module makes the voltage to both connections
high or both connections low, the mode door stops
and will not move. These same motor connections
also provide a feedback signal to the front heater-A/C

POWER MODULE
DESCRIPTION
A blower power module is used on this model when
it is equipped with the optional Automatic Tempera-
ture Control (ATC) (Fig. 12). Models equipped with
the standard manual heater-A/C control use a blower
motor resistor, instead of the blower power module.
The blower power module is installed in a mounting
hole in the back of the rear heater-A/C unit housing,
directly above the expansion valve. The module con-
sists of a molded plastic mounting plate with two
integral connector receptacles. Concealed behind the
mounting plate within the evaporator housing is the
power module electronic circuitry and a large finned,
heat sink. The module mounting plate is secured
with two screws to the rear heater-A/C unit housing
and is accessed for service by removing the right
quarter and D-pillar trim panels.The power module heat sink will get hot when in
use. Do not touch the heat sink if the blower motor
has been running. The blower power module cannot
be adjusted or repaired and, if faulty or damaged, it
must be replaced.
OPERATION
The blower power module is connected to the vehi-
cle electrical system through a dedicated take out
and connector of the rear HVAC wire harness. A sec-
ond connector receptacle receives the pigtail wire
connector from the blower motor. The blower power
module allows the microprocessor-based Automatic
Temperature Control (ATC) heater-A/C control mod-
ule to calculate and provide infinitely variable blower
motor speeds based upon either manual blower
switch input or the ATC programming using a Pulse
Width Modulated (PWM) circuit strategy. The PWM
