2004 NISSAN TERRANO engine

Control Operation
FAN CONTROL DIAL
This DIAL turns the fan ON and OFF, and controls fan speed.
AIR CONTROL DIAL
This DIAL allows outlet air to flow.
TEMPERATURE CONTROL DIAL
This DIAL allows the temperature of the outlet air to be adjusted.
AIR RECIRCULATION SWITCH
OFF position:
Outside air is drawn into the passenger compartment.
ON position (Indicator light ON):
Interior air is recirculated inside the vehicle.
AIR CONDITIONER SWITCH
Start the engine, turn the fan control dial to the desired (1 to 4) position and press the air conditioner switch
to turn ON the air conditioner. The indicator light will come on when the air conditioner is ON. To stop the air
conditioner, push the switch again to return it to the original position.
The air conditioner cooling function operates only when the engine is running.

Lubrication Oil
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
ILack of oil: May lead to a seized compressor
I Excessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.
START
Can oil return operation be performed?
IA/C system works properly.
I There is no evidence of a large amount
of oil leakage.
No
EYe s
Perform oil return operation, proceeding as follows:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 1. Start engine, and set the following conditions:
I Test condition
Engine speed: Idling to 1,200 rpm
A/C or AUTO switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is 25 to
30ÉC (77 to 86ÉF).]
2. Perform oil return operating for about 10 minutes.
3. Stop engine.
CAUTION:
If excessive oil leakage is noted, do not perform the oil return operation.
Should the compressor be replaced?
No Yes
qA(Go to next page.)
Is there any part to be replaced?
(Evaporator, condenser, liquid tank or in
case there is evidence of a large amount
of oil leakage.)
No
EYe s After replacing any of the following major components of the system, be sure
to add the correct amount of oil to the system.
Amount of oil to be added
*1: If compressor is replaced, addition of oil is included in the flow chart.
*2: If refrigerant leak is small, no addition of oil is needed. ªRatioº in this table indicates the ratio of added oil to the overall amount of oil needed in the
system.
Carry out the A/C performance test.F

Operation Check
The purpose of the operational check is to confirm that the system
is as it should be. The systems which will be checked are the
blower, mode (discharge air), intake air, temperature decrease,
temperature increase and A/C switch system.
CONDITIONS:
Engine running and at normal operating temperature.
PROCEDURE:
1. Check blower
1) Turn FAN CONTROL DIAL to 1.Blower should operate at speed 1.
2) Then turn the DIAL to speed 2.
3) Continue checking blower speed until all speeds are checked.
4) Leave blower on speed 4.
2. Check discharge air
1) Turn AIR CONTROL DIAL toposition.
2) Confirm that all discharge air comes out of face vents.
3) Turn AIR CONTROL DIAL to
position.
4) Confirm that discharge air comes out of face vents and foot vents.
5) Turn AIR CONTROL DIAL to
position.
6) Confirm that discharge air comes out of foot vents, with some air from face vents.
7) Turn AIR CONTROL DIAL to
position.
8) Confirm that discharge air comes out of foot vents with some air from defroster vents.
9) Turn AIR CONTROL DIAL to
position.
10) Confirm that all discharge air comes out of defroster vents, with some air from face vents.
3. Check recirculation
1) Switch AIR RECIRCULATION SWITCH to ON position (Indica-tor light ON).
2) Listen for intake door position change (you should hear sound change slightly).
