6-186 ENGINE GENERAL INFORMATION AND DIAGNOSIS
Step
3 Check A/C condenser fan control system.
1) Run engine and warm up it normal operat-
ing temperature.
2) Turn ON lighting switch and blower motor
switch.
3) Check that A/C condenser fan motor and
radiator fan motor operation as follows.
• A/C condenser fan motor and radiator fan
motor is low speed drive for 2 seconds
when A/C switch is ON with engine idling.
• A/C condenser fan motor is high speed
drive and radiator fan motor is stopped after
2 seconds when A/C switch is ON with
engine idling.
Is check result satisfactory?
4 Check A/C Refrigerant
1) Check amount of A/C refrigerant referring to
"Refrigerant charge" in Section 1B.
Is it in good condition?
5 Check A/C Condenser Fan Relay
1) Check A/C condenser fan relay No.1 and
No.2 referring to "Condenser Cooling Fan
Relay (No.1 and No.2) Inspection" in Sec-
tion 1B.
Are check result in good condition?
6 Check Main Fuse
1) Remove main (20 A) fuse from relay/fuse
box.
Is it in good condition?
7 Check Wire Circuit
1) Remove A/C condenser fan relay No.1 and
No.2 with ignition switch turned OFF. (See
Fig. 1.)
2) Turn ON ignition switch, measure voltage
between "BLU/WHT" wire terminal of A/C
condenser fan relay No.1 connector and
vehicle body ground, "BLU/WHT" wire ter-
minal of A/C condenser fan relay No.2 con-
nector and vehicle body ground.
Are voltage 10 – 14 V?
8 Check Wire Circuit
1) Disconnect A/C condenser fan motor con-
nector with ignition switch turned OFF.
2) Measure resistance between "BLU" wire
terminal of A/C condenser fan relay No.1
connector and "BLU" wire terminal of A/C
condenser fan motor connector.
Is resistance 1Ω or less?
Action Yes
A/C condenser fan control
system is in good condi-
tion.
