Action
Clean oily plate using cleaning agent.
Charge battery or check for cause.
Check wire continuity
Check A/C switch and fan switch for continuity and ground.
DEFECTIVES IN FAN MOTOR CIRCUIT
Fan Motor Does Not Run
Checks
Blown fuse
Battery voltage is low
Faulty wiring
Faulty groundAction
Check for short and replace fuse.
Check battery voltage.
Check connectors’ connection.
Do not apply grease. This can cause voltage down.
Remove body painting and completely ground,
Tighten ground bolts and make sure body ground connection.
Checks
Blown resister temperature fuse
Air leakage in parts connection
Action
Replace resistor.
Check heater, cooling unit and blower for proper connection.
Fan Motor Runs in ‘4’position Only (‘3’, ‘2’, ‘1’ : Does Not Run)
Frosted Evaporator
DEFECTIVES IN COMPRESSOR CIRCUIT
Compressor Does Not Run
Checks
Faulty thermo ampAction
Frosted evaporator reduces cooling capacity.
Off compressor and maximize blowing capacity
Checks
Faulty high/low pressure
Faulty A/C relayAction
Check compressor magnet voltage supply.

Checks
Oily clutch plate
Low voltage
Faulty electric connection or operation
Magnetic Clutch Slips /Idles
Checks
Clogged or blocked intake grilleAction
Clogged or blocked intake grille reduces blowing capacity.
Motor Runs With Poor Blowing
Checks
Excessive clearance between
Clutch plate and clutch coilAction
Adjust clutch clearance (0.2-0.6mm).

AIR BAG CONTROL UNIT(AC4)
Removal & Installation Procedure
AC4 is installed on the center portion of the front floor tunnel.
Built-in accelerometer sensor detects collision and determines
action or non-action and ignition time.
Notice
Do not disassemble the AC4 to repair. If defective, replace it.
AC4 should not be shocked or vibrated by dropping on the
ground or bumping.
Replace the AC4 with new after air bag inflation.
1. Disconnect the negative battery cable and wait for 30
seconds before starting service.
Notice
Though battery cable is disconnected, air bag control unit
will maintain backup power for 150ms and air bag can be
inflated, so wait for min.30 seconds.
2. Remove the console box and center fascia panel assembly.
3. Remove the heater control switch and audio assembly.
4. Remove the lower side panel of the driver’s portion and
glove box.
5. Remove the lower main panel.
6. Release the lock lever of the AC4 connector and disconnect
the connector.
7. Unscrew 3 nuts and remove the AC4.
Notice
For installation, horizontal position should be secured for
the better changes of collision pulse between the vehicle
body and air bag control unit.
8. Installation should follow the removal procedure in the
reverse order.
Inspection Procedure
1. Check AC4 case and welt bolts for crack or deformation.
2. Check connector, lock lever and terminal for deformation.
Notice
Replace the AC4 with new if dust, deformation or corrosion
found.
