A/C Auto Amp. Self-DiagnosisINFOID:0000000003775340
A/C SYSTEM SELF-DI AGNOSIS FUNCTION
The self-diagnosis function is built into the A/C auto amp. to quickly locate the cause of malfunctions.
DESCRIPTION
The self-diagnostic system diagnoses sensors, CAN system, and battery voltage on A/C auto amp. Refer to
applicable sections (items) for details. Fault codes (if any are present) will be displayed in the ambient temper-
ature display area. Refer to HAC-24, "
A/C System Self-Diagnosis Code Chart".
SELF-DIAGNOSTIC MODE
NOTE:
Radio must be off.
1. On the A/C and AV switch assembly, press the "SETTING" but- ton and twist the volume knob clockwise and counterclockwise
until the Self-Diagnosis screen shows on the display.
2. Scroll down to "Confirmation/Adjustment" and press the "ENTER" button.
3. Scroll down to "Climate Control" and press the "ENTER" button.
4. The fan bars will flash on the display during the self-test, and then the fault codes will display in the ambient temperature area.
They will continue scrolling until diagnostic mode is exited.
5. Exit by pressing the "BACK" button on A/C and AV switch assembly until display returns to its normal operation screen.
HVAC system will be OFF.

AIR MIX DOOR MOTOR
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.

Blower Speed Compensation - Sunload
When the in-vehicle temperature and the set temperature
are very close, the blower will be operating at low
speed. The speed will vary depending on the sunload. Duri ng conditions of low or no sunload, the blower
operates at low speed. During high sunload conditions , the A/C auto amp. causes the blower speed to
increase.
Blower Speed Control Specification
COMPONENT DESCRIPTION
Variable Blower Control
The variable blower control is located on the cooling unit. The vari-
able blower control receives a gate voltage from the A/C auto amp.
to steplessly maintain the blower motor voltage in the 0 to 5 volt
range (approx.).
Front Blower Motor Component Function CheckINFOID:0000000003775357
INSPECTION FLOW
1.CONFIRM SYMPTOM BY PERFORMING OPERATIONAL CHECK - FRONT BLOWER
1. Push blower motor (+) switch. Blower motor should operate.
2. Rotate the front blower control dial clockwise, and continue checking blower speed and fan symbol until
all speeds are checked.
Can the symptom be duplicated?
YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK FOR ANY SYMPTOMS
Perform a complete operational check for any symptoms. Refer to HAC-4, "
Operational Check (Front)".
Does another symptom exist?
YES >> Refer to HAC-3, "How to Perform Trouble Diagnosis For Quick And Accurate Repair".
NO >> System OK.
3.CHECK FOR SERVICE BULLETINS
Check for any service bulletins.
>> GO TO 4.
4.PERFORM A/C AUTO AMP. SELF-DIAGNOSIS
Perform self-diagnosis to check for any codes. Refer to HAC-23, "
A/C Auto Amp. Self-Diagnosis".
Are any self-diagnosis codes present?

HAC-124
< 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:0000000003775401
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.

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.
 Refer to BRC-8, "ADJUSTMENT OF STEERING ANGLE SEN-
SOR NEUTRAL POSITION : Special Repair Requirement" for
steering angle sensor adjustment.
 Align spiral cable correctly when installing steering wheel. Make sure 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.
 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)
