HEATING / AIR CONDITIONING  AIR CONDITIONING SYSTEM(for Automatic Air Conditioning System)  Blower Motor does not Operate  


DESCRIPTION

If no air is discharged even when the air conditioning control assembly is operated, the following causes are possible.

Malfunction Status Factor
No air is discharged.
·

Blower with fan motor sub-assembly malfunction (+B and GND circuit)

·

Control signal malfunction between air conditioning assembly and blower with fan motor sub-assembly

·

Blower with fan motor sub-assembly malfunction

·

Air conditioning control assembly malfunction

·

Warm-up control

·

Water temperature sensor malfunction



PROCEDURE

1.CHECK AIR CONDITIONING SYSTEM (MANUAL MODE)
a.

Operate the manual mode to check that the blower with fan motor sub-assembly is operated normally.

OK:

Blower with fan motor sub-assembly is operated normally with manual mode.

Coolant Temperature Engine coolant temperature Min.: -40°C (-40°F), Max.: 140°C (284°F) 75 to 100°C (167 to 212°F): After warming up This is the engine coolant temperature.
HINT:
·

After warming up the engine, the engine coolant temperature will be 75 to 100°C (167 to 212°F).

·

After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.

·

If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted.

·

Check if the engine overheats if the value indicated is higher than 135°C (275°F).
