AIR CONDITIONER CONTROL
Revision: November 20092006 QX56
DISPLAY SCREEN
Displays the operational status of the system.
AUTO SWITCH

The compressor, intake door, air mix doors, outlet doors and blower speed are automatically controlled so
that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the oper-
ator.

When pressing AUTO switch, air inlet, air outlet, blower speed, and discharge air temperature are auto-
matically controlled.
TEMPERATURE CONTROL DIAL (TEMPERATURE CONTROL) (DRIVER SIDE)
Increases or decreases the set temperature.
TEMPERATURE CONTROL DIAL (TEMPERATURE CONTROL) (PASSENGER SIDE)
Increases or decreases the set temperature.
TEMPERATURE CONTROL DIAL (TEMPERATURE AND MODE CONTROL) (REAR)
Increases or decreases the set temperature. The mode also changes from foot at full hot setting, to foot/vent
mid-range (warm) setting, and then to panel on full cold setting.
RECIRCULATION () SWITCH

When REC switch is ON, REC switch indicator turns ON, and air inlet is set to REC.

When REC switch is turned OFF, or when compressor is turned from ON to OFF, REC switch is automati-
cally turned OFF. REC mode can be re-entered by pressing REC switch again.

REC switch is not operated when DEF switch is turned ON, at the D/F position or in floor position.
DEFROSTER () SWITCH
Positions the air outlet doors to the defrost position. Also positions the intake doors to the outside air position.
REAR WINDOW DEFOGGER SWITCH
When switch is ON, rear window and door mirrors are defogged.
OFF SWITCH
The compressor and blower are OFF, the intake doors are set to the outside air position, and the air outlet
doors are set to the foot (75% foot and 25% defrost) position.
A/C SWITCH
The compressor is ON or OFF.
(Pressing the A/C switch when the AUTO switch is ON will turn off the A/C switch and compressor.)
MODE SWITCH (FRONT)
Controls the air discharge outlets.
FRONT BLOWER CONTROL DIAL
Manually control the blower speed. Seven speeds are available for manual control (as shown on the display
screen).

CAUTION:
Cap or wrap the A/C refrigerant pipe ends with a suitable material such as vinyl tape to avoid the
entry of air and contaminants.
4. Remove the expansion valve.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:

Replace the O-rings on the A/C refrigerant pipes with new ones, then apply compressor oil to them
when installing them.

After charging refrigerant, check for leaks.
Checking for Refrigerant LeaksEJS003Z5
PRELIMINARY CHECK
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak-
age, damage, and corrosion. Any A/C oil leakage may indicate an area of refrigerant leakage. Allow extra
inspection time in these areas when using either an electronic refrigerant leak detector (J-41995) or fluores-
cent dye leak detector (J-42220).
If any dye is observed using a fluorescent dye leak detector (J-42220), confirm the leak using a electronic
refrigerant leak detector (J-41995). It is possible that the dye is from a prior leak that was repaired and not
properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic refrigerant leak detector (J-41995), move the probe
along the suspected leak area at 25 - 50 mm (1 - 2 in) per second and no further than 6 mm (1/4 in) from the
component.
CAUTION:
Moving the electronic refrigerant leak detector probe slower and closer to the suspected leak area will
improve the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Dye Leak DetectorEJS003Z6
1. Check the A/C system for leaks using the fluorescent dye leak detector and safety goggles (J-42220) in a low sunlight area (area without windows preferable). Illuminate all components, fittings and lines. The dye
will appear as a bright green/yellow area at the point of leakage. Fluorescent dye observed at the evapo-
rator drain opening indicates an evaporator core assembly leak (tubes, core or expansion valve).
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or cloth, then inspect the shop rag or cloth with the fluorescent dye leak detector (J-42220) for dye residue.
3. After the leak is repaired, remove any residual dye using refrigerant dye cleaner (J-43872) to prevent future misdiagnosis.
4. Perform a system performance check and then verify the leak repair using a electronic refrigerant leak detector (J-41995).
NOTE:

Other gases in the work area or substances on the A/C components, for example, anti-freeze, wind-
shield washer fluid, solvents and oils, may falsely trigger the leak detector. Make sure the surfaces to
be checked are clean.

Clean with a dry cloth or blow off with shop air.

Do not allow the sensor tip of the electronic refrigerant leak detector (J-41995) to contact with any sub-
stance. This can also cause false readings and may damage the detector.
Dye InjectionEJS003Z7
NOTE:
This procedure is only necessary when recharging the system or when the compressor has seized and must
be replaced.
1. Check the A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.52 kg/cm
2 , 50 psi).
Expansion valve bolts : 4 N·m (0.41 kg-m, 35 in-lb)

INSTALLATION
Installation is in the reverse order of removal.

Tighten the intake manifold bolts in numerical order as shown.

Install the EVAP canister purge control solenoid valve connector with it facing front of engine.

Tighten the electronic throttle control actuator bolts of the electric throttle control actuator equally and
diagonally in several steps.

After installation perform procedure in EM-20, "INSPECTION AFTER INSTALLATION" .

Install the water hose so that its overlap width for connection is between 27 mm (1.06 in) and 32 mm (1.26
in) (target: 27 mm 1.06 in).
Connecting Quick Connector of Fuel Tube
Install quick connector as follows (the steps are the same for quick connectors on both engine side and vehi-
cle side except for the quick connector cap).
1. Make sure no foreign substances are deposited in and around tube and quick connector, and they are not
damaged.
2. Thinly apply new engine oil around the fuel tube from tip end to the spool end.
3. Align center to insert quick connector straight into fuel tube.

Insert until the paint mark for engagement identification
(white) goes completely inside quick connector so that you
cannot see it from the straight side of the connected part. Use
a mirror to check this where it is not possible to view directly
from the straight side, such as quick connector on vehicle
side.

Insert fuel tube into quick connector until top spool is com-
pletely inside quick connector, and 2nd level spool exposes
right below quick connector on engine side.
CAUTION:

Hold "A" position in illustration when inserting fuel
tube into quick connector.

Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.

Insert until you hear a "click" sound and actually feel
the engagement.

To avoid misidentification of engagement with a similar
sound, be sure to perform the next step.
4. Pull quick connector by hand holding "A" position. Make sure it is completely engaged (connected) so that it does not come out from fuel tube.
NOTE:
Recommended pulling force is 50 N (5.1 kg, 11.2 lb).

FUEL INJECTOR AND FUEL TUBE
2006 QX56

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring.

If O-ring was stretched while it was being attached, do not insert it quickly into fuel tube.

Insert new O-ring straight into fuel tube. Do not twist it.
6. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
After installing the fuel tubes, make sure there are no fuel leaks at the connections using the following steps.
1. Apply fuel pressure to the fuel lines by turning ignition switch ON (with engine stopped). Then check for fuel leaks at the connections.
NOTE:
Use mirrors for checking on hidden points.
2. Start the engine and rev it up and check for fuel leaks at the connections.
CAUTION:
Do not touch the engine immediately after stopping, as engine becomes extremely hot.
