Air Mix Door Control Specification
COMPONENT DESCRIPTION
Air Mix Door Motors (front)
The driver (1) and passenger (2) air mix door motors are attached to
the front heater & cooling unit assembly. These motors rotate so that
the air mix door is opened or closed to a position set by the A/C auto
amp. Motor rotation is then conveyed through a shaft and the air mix
door position is then fed back to t
he A/C auto amp. by the PBR built
into the air mix door motors.
Air Mix Door Motor (rear)
The air mix door motor (rear) (1) is attached to the rear heater &
cooling unit assembly. These motors rotate so that the air mix door is
opened or closed to a position set by the front (or rear) air control.
Motor rotation is then conveyed through a shaft and the air mix door
position is then fed back to the A/C auto amp. by the PBR built into
the air mix door motors.

INSPECTION FLOW
1.CONFIRM SYMPTOM BY PERFORMING OPERAT IONAL CHECK - TEMPERATURE INCREASE
1. Turn the temperature control dial (driver) clockwise until 32 °C (90 °F) is displayed.
2. Check for hot air at discharge air outlets.
>> GO TO 2.
2.CONFIRM SYMPTOM BY PERFORMING OPERAT IONAL CHECK - TEMPERATURE DECREASE
1. Turn the temperature control dial (driver) counterclockwise until 18° C (60°F) is displayed.
2. Check for cold air at discharge air outlets.
Is the inspection result normal?
YES >> Inspection End.
NO >> Go to diagnosis procedure. Refer to HAC-32, "
Air Mix Door Motor (Driver) Diagnosis Procedure".

< PRECAUTION >[AUTOMATIC AIR CONDITIONER]
PRECAUTIONS
If a refrigerant other than pure HFC-134a (R-134a)
is identified in a vehicle, your options are:
• Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into
the atmosphere.
• Explain that recovery of the contaminated refri gerant could damage your service equipment and refrigerant
supply.
• Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
• If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain- ers. Do not recover contamin ated refrigerant into your existing service equipment. If your facility does
not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available ser-
vice. This refrigerant must be disposed of in acco rdance with all federal and local regulations. In addition,
replacement of all refrigerant system components on the vehicle is recommended.
• If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN Cus-
tomer Affairs for further assistance.
Precaution for Service EquipmentINFOID:0000000005147744
MANIFOLD GAUGE SET
Be certain that the gauge face indicates R-134a or 134a. Make sure
the gauge set has 1/2 ″-16 ACME threaded connections for service
hoses. Confirm the set has been used only with refrigerant HFC-
134a (R-134a) along with specified oil.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or aut omatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.

Removal and InstallationINFOID:0000000005147870
REMOVAL
1. Set the front wheels in the straight-ahead position.
2. Remove the driver air bag module. Refer to SR-5, "
Removal and Installation".
3. Disconnect steering wheel switches.
4. Remove the steering wheel center nut.
5. Remove the steering wheel using Tool.
CAUTION:
Place a piece of tape across the sp iral cable so it will not be
rotated out of position.
6. Disconnect heated steering wheel connector.
7. Inspect the steering wheel near the puller holes for damage. If damaged, replace the steering wheel.
• Remove steering wheel rear cover and steering wheelswitches, if required.
INSTALLATION
Installation is in the reverse order of removal.
• Align spiral cable correctly when installing steering wheel. Makesure that the spiral cable is in the neutral position. The neutral
position is detected by turning left 2.5 revolutions from the right
end position and ending with the knob at the top.
• Refer to BRC-8, "
ADJUSTMENT OF STEERING ANGLE SEN-
SOR NEUTRAL POSITION : Special Repair Requirement" for
steering angle sensor adjustment.
• After the work is completed, perform self-diagnosis to make sure no malfunction is detected. Refer to SRC-13, "
SRS Operation
Check".
• Tighten steering wheel center nut to specification. SR-7, "
Removal
and Installation".
CAUTION:
• The spiral cable may snap due to steering operation if the
cable is not installed in the correct position.
• With the steering linkage di sconnected, the cable may snap
by turning the steering wheel beyond the limited number of
turns. The spiral cable can be turned counterclockwise about
2.5 turns from the neutral position. Tool number : ST27180001 (J-25726-A)
