Air Conditioning System -General Information5-75Air conditioner pressure switch plug-in unitInspection1. Check pressure switch
(a) Magnetic clutch control:
Check operation of pressure switch
( 1 ) Install manifold instrument
( 2 ) Connect positive meter pen of ohmmeter to terminal 4,
negative meter pen to terminal 1respectively.
( 3 ) As shown in the figure, check connection of each terminal
when refrigerant pressure changes
If operation does not conform to specification, replace
pressure switch.
(b) Check operation of condenser fan
( 1 ) Connect positive meter pen to terminal 2, negative meter pen to terminal 3 respectively.
( 2 ) As shown in the figure, check connection of each terminal when refrigerant pressure changes
If operation does not conform to specification, replace pressure switch.
2. Compressor magnetic clutch
(a) Connect positive pole of storage battery to binding post, negative pole to compressor shell.
(b) Check magnetic clutch in energized condition.
If abnormal, replace magnetic clutch.
3. Air conditioner thermistorThermistor plug-in unit (a) As shown in the figure, check resistance value of air conditioner thermistor

a. Remove front rear seat, left front doorsill, right front doorsill, right center lower pillar lower trim, left center
pillar lower trim, right rear doorsill shield, left rear doorsill shield, frontal and rear parts of auxiliary fascia
console;
b. Remove the sound insulator assembly under carpet and dash, the dash heat insulation (in compartment).
2. Mounting
a. Mount accelerator pedal assembly, brake and clutch pedal assembly, brake assembly onto the car;
b. Install the carpet according to the corresponding holes with its left and right edges mounted separately under
the left front doorsill shield, the right front doorsill shield, the right center pillar lower trim, the left center
pillar lower trim, right rear doorsill shield and the left rear doorsill shield.

It is mainly used to install the pipes and accessories of the brake system and clutch system.
5. Front wall upper assembly
The front wall upper assembly includes left/right hinge base mounting plate big assembly, front wall upper
front cover big assembly, VIN number mounting plate, and front wall upper rear cover big assembly etc.
It forms a high-stiffness frame structure together with the engine compartment assembly and the front wall
lower plate assembly. It can generate strong resistant to the transverse collision and rolling deformation. It can also
separate the engine compartment form the cabin, preventing the odor entering into the cabin. Consequently, it can
isolate the noise, heat and vibration.(2) Floor Assembly The floor assembly is the base work of the main structure. It is a key component that connects various
assemblies and carries the load. The vehicle performance is subject to its strength and stiffness. For the floor
assembly, see the Fig. 5-3.
The floor assembly includes front floor assembly and rear floor assembly. The front floor mid-block goes
through a ridgy channel in longitudinal direction. It can increase the longitudinal rigidity together with the lower
floor longitudinal beam. The space below under the channel is used to install various parts and components, such
as transmission gearshift rod, parking brake cable, discharge pipe with three-way catalytic converter etc. In the
cabin, there is carpet and muffle pad. The floor frame structure is made up of front floor left/right frame, front floor
main plate assembly, front floor mid-bridge assembly, rear frame assembly, rear floor rear block assembly, rear
floor mid-block assembly and longitudinal beam etc. These parts and components provide strong and reliable carry
capacity and ensure that the vehicle meets the strict driving requirement on the body.Fig. 5-3 Floor Assembly
