HEATING / AIR CONDITIONING  AIR CONDITIONING SYSTEM(for Automatic Air Conditioning System)  Recirculated/Fresh Air Modes do not Switch  


DESCRIPTION

If the fresh/recirculation mode does not change or exhaust gas can be smelled even while set to recirculation mode, the following causes are possible.

Malfunction Status Factor
·

Fresh/recirculation mode does not change.

·

Fresh/recirculation mode does not change automatically.

·

Exhaust gas can be smelled even while set to recirculation mode.


·

Blower servo motor malfunction

·

Blower damper and link operation (jamming)

·

Foreign object jammed in door

·

Air conditioning radiator sub-assembly malfunction

·

High engine coolant temperature



PROCEDURE

1.CHECK NO. 1 BLOWER DAMPER SERVO SUB-ASSEMBLY
a.

Check that the No. 1 blower damper servo sub-assembly is installed correctly.

OK:

No. 1 blower damper servo sub-assembly is installed correctly.

Tester Display Measurement Item Range Normal Condition Diagnostic Note
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).
