BLEND DOOR ACTUATOR
DESCRIPTION
The blend door actuators are reversible, 12-volt
Direct Current (DC), servo motors. Models with the
single zone heater and air conditioner system have a
single blend air door, which is controlled by a singleblend door actuator. Models with the optional dual
zone front heater and air conditioner system have
dual blend air doors, which are controlled by two
blend door actuators. The single zone blend door
actuator is located on the driver side end of the heat-
er-A/C housing unit, close to the dash panel. In the
dual zone system, the same blend door actuator used
for the single zone system becomes the passenger
blend door actuator, and is mechanically connected to
only the passenger side blend air door. In the dual
zone system, a second separate blend door actuator is
also located on the driver side end of the heater-A/C
housing unit close to the instrument panel, and is
mechanically connected to only the driver side blend
air door.
The blend door actuators are interchangeable with
each other, as well as with the actuators for the
mode door and the recirculation air door. Each actua-
tor is contained within an identical black molded
plastic housing with an integral wire connector
receptacle. Two integral mounting tabs allow the
actuator to be secured with two screws to the heater-
A/C unit housing. Each actuator also has an identical
output shaft with splines that connects it to the link-
age that drives the proper blend air door. The blend
door actuators do not require mechanical indexing to
the blend door linkage, as they are electronically cal-
ibrated by the heater-A/C control module. The blend
door actuators cannot be adjusted or repaired and, if
damaged or faulty, they must be replaced.
OPERATION
Each blend door actuator is connected to the heat-
er-A/C control module through the vehicle electrical
system by a dedicated two-wire take out and connec-
tor of the HVAC wire harness. The blend door actua-
tor can move the blend air door in two directions.
When the heater-A/C control module pulls the volt-
age 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 module makes
the voltage to both connections high or both connec-
tions low, the blend air door stops and will not move.
These same motor connections also provide a feed-
back signal to the heater-A/C control 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 heater-A/C con-
trol 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 circuits. The blend
door actuator can be diagnosed using a DRBIIItscan
tool. Refer to the appropriate diagnostic information.

it to the linkage that drives the mode door. The mode
door actuator does not require mechanical indexing
to the mode door linkage, as it is electronically cali-
brated by the heater-A/C control module. The mode
door actuator cannot be adjusted or repaired and, if
damaged or faulty, it must be replaced.
OPERATION
The mode door actuator is connected to the heater-
A/C control module through the vehicle electrical sys-
tem by a dedicated two-wire take out and connector
of the HVAC wire harness. The mode door actuator
can move the mode door in two directions. When the
heater-A/C control module pulls the voltage on one
side of the motor connection high and the other con-
nection low, the mode door will move in one direction.
When the module 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 heater-A/C control module. This feedback signal
allows the module to monitor the operation and rela-
tive position of the mode door actuator and the mode
door. The heater-A/C control module learns the mode
door stop positions during the calibration procedure
and will store a Diagnostic Trouble Code (DTC) for
any problems it detects in the mode door actuator
circuits. The mode door actuator can be diagnosed
using a DRBIIItscan tool. Refer to the appropriate
diagnostic information.

RECIRCULATION DOOR
ACTUATOR
DESCRIPTION
The recirculation door actuator is a reversible,
12-volt Direct Current (DC), servo motor (Fig. 23).
The single recirculation door actuator is located on
the passenger side end of the heater-A/C housing
unit, on the bottom of the lower intake air housing.
The recirculation door actuator is mechanically con-
nected to the recirculation air door. The recirculationdoor actuator is interchangeable with the actuators
for the blend air door(s) and the mode door. Each
actuator is contained within an identical black
molded plastic housing with an integral wire connec-
tor receptacle. Two integral mounting tabs allow the
actuator to be secured with two screws to the lower
intake air housing. Each actuator also has an identi-
cal output shaft with splines that connects it to the
linkage that drives the recirculation air door. The
recirculation door actuator does not require mechan-
ical indexing to the recirculation air door, as it is
electronically calibrated by the heater-A/C control
module. The recirculation door actuator cannot be
adjusted or repaired and, if damaged or faulty, it
must be replaced.
OPERATION
The recirculation door actuator is connected to the
heater-A/C control module through the vehicle elec-
trical system by a dedicated two-wire take out and
connector of the HVAC wire harness. The recircula-
tion door actuator can move the recirculation door in
two directions. When the heater-A/C control module
pulls the voltage on one side of the motor connection
high and the other connection low, the recirculation
air door will move in one direction. When the module
reverses the polarity of the voltage to the motor, the
recirculation air door moves in the opposite direction.
When the module makes the voltage to both connec-
tions high or both connections low, the recirculation
air door stops and will not move. These same motor
connections also provide a feedback signal to the
heater-A/C control module. This feedback signal

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 door
actuator 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
