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.

OK:

The blower motor with fan sub-assembly operates normally.

GO TO OTHER DIAGNOSIS PROCEDURE (Blower Motor Circuit)

2.	READ VALUE USING TECHSTREAM

(a) Connect the Techstream to the DLC3.

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).
