REMOVAL
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deploymentand possible personal injury or
death.
1. Disconnect and isolate the negative battery cable.
2. Remove the glove box from the instrument panel
(Refer to 23 - BODY/INSTRUMENT PANEL/
GLOVE BOX - REMOVAL).
3. Remove the two screws (1) that secure the recircu-
lation door actuator (2) to the side of the HVAC air
inlet housing (3).
4. Remove the recirculation door actuator from the air
inlet housing and disconnect the HVAC wire har-
ness connector (4) from the actuator.
5. Remove the recirculation door actuator from the
vehicle.
INSTALLATION
1. Install the recirculation door actuator (1) onto the
side of the HVAC air inlet housing (2). If necessary,
rotate the actuator slightly to align the splines on
the actuator output shaft (3) with those in the recir-
culation door actuator coupler (4).

CLUTCH-A/C COMPRESSOR
DESCRIPTION
NOTE: Denso 10S17 A/C clutch assembly shown.
Visteon HS-18 compressor similar.
The A/C compressor clutch assembly consists of a
stationary electromagnetic field coil (4), bearing and
pulley assembly (3), shims (7) and a clutch plate (2)
that is splined to the compressor shaft and secured by
a bolt (1). These components provide the means to
engage and disengage the A/C compressor from the
engine accessory drive belt.
The A/C clutch bearing and pulley assembly on both
A/C compressors are retained to the front of the com-
pressor with a snap ring (6). The A/C clutch field coil
on the Denso 10S17 A/C compressor is also retained
to the front of the compressor using a snap ring (5).
The field coil on the Visteon HS-!8 compressor is
pressed onto the front of the compressor.
OPERATION
The A/C compressor clutch components provide the means to engage and disengage the A/C compressor from the
engine accessory drive belt. When the electromagnetic A/C clutch field coil is energized, it magnetically draws the
clutch plate into contact with the clutch pulley and drives the compressorshaft. When the coil is not energized, the
pulley freewheels on the clutch hub bearing, which is part of the pulley assembly.
A/C compressor clutch engagement is controlled by the powertrain controlmodule (PCM) or the engine control mod-
ule (ECM), depending on engine application. When the A/C-heater control is set to any A/C position, it sends a
request signal on the CAN-B bus to the totally integrated power module (TIPM), which then transfers the request on
the CAN-C Bus to the PCM/ECM, which determines if operating conditions arecorrect for A/C clutch engagement.
When all operating conditions have been met, the PCM/ECM sends a signal on adedicated hard-wired circuit back
to the totally integrated power module (TIPM) to energize the internal A/Cclutch high side driver. When energized,
the A/C clutch high side driver provides battery current to the A/C clutch field coil.
The A/C clutch control system is diagnosed using a scan tool (Refer to 24 - HVAC Electrical Diagnostics and to 9
- Engine Electrical Diagnostics for more information).
The A/C compressor clutch components cannot be repaired and, if faulty or damaged, they must be replaced.
DIAGNOSIS AND TESTING
A/CCOMPRESSORCLUTCHCOIL
The A/C compressor clutch coil electrical circuit is controlled by the powertrain control module (PCM) or the engine
control module (ECM) (depending on engine application) through the totally integrated power module (TIPM) (Refer
to 24 - HEATING & AIR CONDITIONING/CONTROLS/COIL-A/C COMPRESSOR CLUTCH -OPERATION for more
information). Begin testing of a suspected compressor clutch coil problem by performing the preliminary checks.
PRELIMINARY CHECKS
1. Using a scan tool, check for diagnostic trouble codes (DTCs) in the A/C-heater control, TIPM, PCM/ECM and if
equipped with the 8.3L engine, the gateway module. If no DTCs are found, go to Step 2. If any DTCs are found,
repair as required.
2. If the A/C compressor clutch still will not engage, verify the refrigerant charge level (Refer to 24 - HEATING &
AIR CONDITIONING/PLUMBING - DIAGNOSIS AND TESTING - REFRIGERANT SYSTEM LEAKS). If the refrig-
erant charge level is OK, go to TESTS . If the refrigerant charge level is notOK, adjust the refrigerant charge as
required.

The A/C-heater control is diagnosed using a scan tool (Refer to 24 - HEATING& AIR CONDITIONING - DIAGNO-
SIS AND TESTING and to 24 - HVAC Electrical Diagnostics for more information).
The A/C-heater control cannot be repaired and, if faulty or damaged, it must be replaced. The illumination lamps for
the A/C-heater control are available for service replacement.

RESISTOR-BLOWER MOTOR
DESCRIPTION
The blower motor resistor is mounted to the bottom of
the HVAC housing, directly behind the glove box. The
blower motor resistor consists of a molded plastic
mounting plate (1) with an integral wire connector
receptacle (2). Concealed behind the mounting plate
are coiled resistor wires contained within a ceramic
heat sink (3).
OPERATION
The blower motor resistor is connected to the vehicle electrical system through a dedicated wire lead and connector
of the HVAC wire harness. The blower motor resistor has multiple resistor wires, each of which will reduce the
current flow through the blower motor to change the blower motor speed.
The blower motor control for the heating-A/C system directs the ground path for the blower motor through the cor-
rect resistor wire to obtain the selected speed. With the blower motor control in the lowest speed position, the
ground path for the blower motor is applied through all of the resistor wires. Each higher speed selected with the
blower motor control applies the blower motor ground path through fewer ofthe resistor wires, increasing the blower
motor speed.
The blower motor resistor cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.
DIAGNOSIS AND TESTING
BLOWER MOTOR RESISTOR
WARNING: On vehicles equipped with airbags, disable the airbag system before attempting any steering
wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the
negative battery (ground) cable, then wait two minutes for the airbag system capacitor to discharge before
performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to
take the proper precautions could result in accidental airbag deploymentand possible personal injury or
death.
NOTE: For circuit descriptions and diagrams, refer to the appropriate wiring information. The wiring infor-
mation includes wiring diagrams, proper wire and connector repair procedures, further details on wire har-
ness routing and retention, as well as pin-out and location views for the various wire harness connectors,
splices and grounds.
1. Disconnect and isolate the negative battery cable.
2. Disconnect the wire harness connector from the blower motor resistor (Refer to 24 - HEATING & AIR CONDI-
TIONING/CONTROLS/RESISTOR-BLOWER MOTOR - REMOVAL).

3. Using an ohmmeter, check for continuity between all of the blower motor resistor terminals. In each case there
should be continuity. If OK, repair the wire harness circuits between the blower motor speed control and the
blower motor resistor or blower motor as required. If not OK, replace the faulty blower motor resistor.
