DESCRIPTION
If air does not flow from the front registers after the blower switch on the air conditioning control assembly is operated, the following suspected areas may be the cause.
|
Symptom | Factor |
|
No air flows from the registers |
- Air conditioning amplifier assembly malfunction
- Blower motor with fan sub-assembly malfunction
- Air conditioning control assembly malfunction
- Clogged clean air filter
- Clogged No. 1 evaporator sub-assembly or heater radiator unit sub-assembly fins

PROCEDURE
| 1. |
CHECK AIR CONDITIONING SYSTEM (MANUAL MODE) |
(a) Turn off the AUTO switch, operate the blower switch and check that the blower motor with fan sub-assembly can be operated manually.

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).

DESCRIPTION If the airflow from the front registers is weak regardless of the blower speed setting displayed on the air conditioning control assembly, the following suspected areas may be the cause.
DESCRIPTION Based on signals from the air conditioner pressure sensor, the air conditioning amplifier assembly controls the compressor assembly with pulley (compressor solenoid)*1 or cooler compressor
DESCRIPTION If the air inlet mode cannot be changed between recirculation/fresh or exhaust gas odors can be smelled even though recirculation mode is selected, the following suspected areas may be the
