INSUFFICIENT HEATING

Description

INFOID:0000000007563453

Symptom

• Insufficient heating
• No warm air comes out. (Air flow volume is normal.)

Diagnosis Procedure

INFOID:0000000007563454

NOTE:
Perform self-diagnoses with CONSULT before performing symptom diagnosis. If any DTC is detected, per-
form the corresponding diagnosis.

1.

CHECK COOLING SYSTEM

1.

Check engine coolant level and check for leakage. Refer to 

CO-8, "Inspection"

.

2.

Check radiator cap. Refer to the 

CO-12, "RADIATOR CAP : Inspection"

.

3.

Check water flow sounds of the engine coolant. Refer to 

CO-9, "Refilling"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Refill engine coolant and repair or replace the parts depending on the inspection results.

2.

CHECK HEATER HOSE

Check installation of heater hose by visually or touching.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace parts depending on the inspection results.

3.

CHECK HEATER CORE

1.

Check temperature of inlet hose and outlet hose of heater core.

2.

Check that inlet side of heater core is hot and the outlet side is slightly lower than/almost equal to the inlet
side.

CAUTION:

Always perform the temperature inspection in a short period of time because the engine coolant
temperature is very hot.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Replace heater core. Refer to 

HA-49, "HEATER CORE : Removal and Installation"

.

4.

CHECK AIR LEAKAGE FROM EACH DUCT

Check duct and nozzle, etc. of the air conditioning for air leakage.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace parts depending on the inspection results.

5.

CHECK SETTING OF TEMPERATURE SETTING TRIMMER

1.

Check setting value of temperature setting trimmer. Refer to 

HAC-34, "Temperature Setting Trimmer"

. 

2.

Check that temperature setting trimmer is set to “

−

 direction”. 

NOTE:
The control temperature can be set by the temperature setting trimmer.

3.

Set difference between the set temperature and control temperature to “0”.

Are the symptoms solved?

YES

>> INSPECTION END

NO

>> Replace A/C auto amp. Refer to 

HAC-78, "Removal and Installation"

.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000007565496

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.
