up the engine.
2. Check that warm air blows from the outlets.
Is the inspection result normal?
YES >> END.
NO >> GO TO 3.
3.CHECK SETTING OF TEMPERATURE SETTING TRIMMER
Using CONSULT-III, check the setting of “TEMP SET CORRECT” on “WORK SUPPORT” of HVAC. Refer to
HAC-10, "
Temperature Setting Trimmer".
1. Check that the temperature setting trimmer is set to “− direction”.
NOTE:
The control temperature can be set by the temperature setting trimmer.
2. Set temperature control switch to “0”.
Are the malfunction solved?
YES >> Perform the setting separately if necessary. END.
NO >> GO TO 4.
4.CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT-III
1. Using CONSULT-III, perform “SELF-DIAGNOSIS RESULTS” of HVAC.

NOTE:
If DTC is displayed along with DTC U1000 or U1010, first diagnose the DTC U1000 or U1010. Refer to
HAC-42, "
DTC Logic" or HAC-43, "DTC Logic".
Is any DTC displayed?
YES >> Perform the diagnosis that is applicable to the sensor and the door motor. Refer to HAC-85, "DTC
Index".
NO >> GO TO 5.
5.CHECK WITH ACTIVE TEST OF CONSULT-III
1. Using CONSULT-III, perform “HVAC TEST” in “ACTIVE TEST” of HVAC to check each output device.
Refer to HAC-38, "
CONSULT-III Function".
NOTE:
Perform the ACTIVE TEST after starting the engine because the compressor is operated.
2. Refer to the table and check the outlet, inlet, air flow temperature, blower motor control signal, magnet
clutch operation, and air mix ratio. Visually check each operating condition, by listening for noise, touching
air outlets with a hand, etc.

 Explain that recovery of the contaminated refrigerant could damage service equipment and refrigerant sup-
ply.
 Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
 If repairing, recover the refrigerant using only dedicated equipment and containers. Never reintroduce
contaminated refrigerant into the existing service equipment. Contact a local refrigerant product retailer
for available service if the facility does not have dedicated recovery equipment. This refrigerant must be dis-
posed of in accordance with all federal and local regulations. In addition, replacement of all refrigerant sys-
tem components on the vehicle is recommended.
 The air conditioner warranty is void if the vehicle is within the warranty period. Please contact Nissan Cus-
tomer Affairs for further assistance.
General Refrigerant PrecautionINFOID:0000000003846400
WARNING:
 Never breath A/C refrigerant, lubricant vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) from the A/C system, using certified service equipment meeting require-
ments of SAE J-2210 [HFC-134a (R-134a) recycling equipment], or J-2209 [HFC-134a (R-134a) recov-
ery equipment]. Ventilate work area before resuming service if accidental system discharge occurs.
Additional health and safety information may be obtained from refrigerant and lubricant manufactur-
ers.
 Never release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant each time an air conditioning system is discharged.
 Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
 Never store or heat refrigerant containers above 52°C (126°F).
 Never heat a refrigerant container with an open flame. Place the bottom of the container in a warm
pail of water if container warming is required.
 Never intentionally drop, puncture, or incinerate refrigerant containers.
 Keep refrigerant away from open flames. Poisonous gas is produced if refrigerant burns.
 Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo-
cation.
 Never pressure test or leakage test HFC-134a (R-134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refriger-
ant manufacturers.
