1. Configuration introduction
The GWFLORID comes in three configurations: comfort, luxury and elite. The wire harness has two types of
configurations: One is a non jam protection comfort model, which is a combination of both comfort and luxury
type, the other type is called elite. These two configurations are universally used in most of this manual. The
parts that are only available for the non jam protection comfort type have been marked in this manual, please
pay attention to these sections while performing maintenance.
2. Fuse box and power supply introduction
The fuse box located inside the left side of the dashboard is No. 1 Fuse Box, the other one inside the left side of
the engine compartment is No. 2 Fuse Box.
• 30 represents a power cord for normal power, which is from the battery positive fuse box-60 A.
• 30a represents a power cord for normal power, which is from the battery positive fuse box-120 A.
• 30b represents a power cord for normal power, which is from the battery positive fuse box-120 A.

Areas of importance in circuit maintenance
1. Before operating any electronic devices, and when tools or maintenance devices may easily make
contact with an uncovered electronic terminal, please make sure to turn the ignition switch to the LOCK
position, and then disconnect the battery's negative cable to avoid injury or vehicle damage. When the
ignition switch is on the ON position, please do not disconnect the battery's connecting wire or take out
the power's fuse, regardless if the engine is running or not.Otherwise it would seriously damage the
ECU and related microelectronic devices such as sensors.
2. When changing the fuse, please make sure that the new fuse possesses the proper current rating,
and is not above or below this rating.
3. When repairing the wire harnesses of the airbag and pretensioner, only specified contact points,
plugs, and wires are allowed to be used.
4. Before repairing the wire harness, make sure to eliminate any factor that might cause damage,
for example, the edge of a vehicle body part is too sharp, or the used electronics are damaged or
corroded.
5. Shielded wire should not be repaired, it must be replaced entirely once it is damaged.
6. Unless it is specified during the test, please do not use an analog multimeter to test the ECU and
sensor, instead use a high-impedance digital multimeter (internal resistance should be ≥10 kΩ) or a
vehicle multimeter for inspection.
7. When inspecting the connector with a digital multimeter, take the waterproof rubber cover off the
connector, and tightly insert the test pen along the connecting terminal. Don't use too much force, as
to avoid cracking the connector.
Circuit inspection steps
The principle of troubleshooting is to confirm the "possible cause". Once the possible cause is confirmed, the
components that need to be inspected are limited to the components that are related to the possible cause. The
confirmed possible cause should be based on theory and be supported by facts, but not just by intuition. If
one tries to solve the problem but does not adopt the proper troubleshooting steps, it may make the problem
worse. Then the possible cause not only can't be confirmed, but also maintenance can't be performed properly.
Troubleshooting should adhere to the four steps below:
1. Observe the symptoms carefully, inspect if there is anything else abnormal, and record it.
2. While confirming the possible causes, study the circuit diagram carefully, and regard it as a whole
system in order to understand the circuit. Thorough knowledge of switches, relays, and other
electronic components is obligatory for proper analysis.
3. Inspect and eliminate the problems one by one until the cause is found.
4. After the malfunction is fixed, make sure to check if the inspected system is working properly, and also
check if the maintenance may have caused any new problems.

Clutch Installation
1. Install the solenoid coil at the place pressing up against the head cover's end surface and pay atten-
tion to insert the dowel pin of the solenoid coil into the bottom hole of the head cover. Put the retaining
ring into the groove with circlip pliers, and press the solenoid coil's connecting wire onto the pressing
line plate on the head cover with a SST.
2. Put the compressor on a specially designed fixture or platform, with its head cover facing upwards.
Press the pulley into the head cover shaft, and put the pulley bearing's retaining ring into the groove
with circlip pliers.
3. Install the armature onto the main shaft's spline and seize the clutch's triangular piece with a clamp.
Then tighten the inner hexagon lock screws and washers with a torque wrench. Screw torque should
be between 150-180 N·m. After installation is done, make sure to check if the clutch's pulley and
armature are able to operate freely, and also check the clearance between the pulley and armature,
which should be 0.3-0.6 mm.
Vacuuming and Charging Refrigerant
Initiate vacuum pumping by using the manifold pressure
gauge connected to the air conditioner (compressor) pipeline
and vacuum pump. When the vacuum pumping starts, open
the manifold pressure gauge's high and low pressure valve,
and open the vacuum pump's end surface valve (if equipped),
then press the "ON" button to start the vacuum pump, and let it
run for at least 20 minutes. When the manifold pressure gauge
shows -760 mmHg or lower, close the high and low pressure
valve, and press the switch to turn off the vacuum pump.

Inspect air tightness
After shutting off the vacuum pump, continue to inspect
the pressure reading of the manifold pressure gauge. If the
pressure reading remains unchanged for 20 minutes after
the vacuum pump stops operating, the refrigeration system
is proven to have no leak. One may continue to the next
step. If the reading changes, the system has a leak. Carry out
an inspection, and after repairing the leaking section, start
vacuum pumping once more.
Charge refrigerant
After verifying the system's air tightness, connect the
refrigerant tank (or gas cylinder) and yellow air supply hose
head. Connect the yellow air supply hose's other head with
the injection port in the middle of the manifold pressure
gauge. Ensure the refrigerant tank and air supply hose's nut
is tightly connected, then open the refrigerant tank's valve.
At this time, the high and low pressure valve is closed. Use
a tip shaped screwdriver or similar instrument and press
the valve core at the side port for 1-2 s, then expel the air
between the air supply hose and manifold gauge.
Perform switch operations according to the
following methods
1. Switch the front and rear blower speed control switch
to the highest settings, and rotate the temperature
control switch to the coldest position.
2. Press down the A/C switch, and set inner/outer circula-
tion to inner circulation mode. Open the doors and win-
dows during this procedure.
3. Adjust the engine's speed to the regulated idle speed.
4. Hold up the refrigerant tank or gas cylinder (emptying
