CONDENSER FAN MOTORS

INSPECTION OF CONDENSER FAN MOTORS

1. DISCONNECT NEGATIVE CABLE FROM BATTERY

2. DISCONNECT CONNECTOR OF FAN MOTOR

3. CHECK FAN MOTOR
(a) Using the wire harness, apply battery voltage (12V) to the connector.
(b) Check the smooth rotation of the motor within the specified current flow.

Standard current:
Fan motor No.1 and No.2
                    6.7 ± 0.7 A  (7M-GTE E/G and M/T model)
                    6.7 ± 0.7 A  (7M-GTE E/G and A/T model or
                                  7M-GE E/G model)

Fan motor No.3
                    6.7 ± 0.7 A  (7M-GTE E/G and A/T model only)

If defective, replace the motor.

4. CONNECT CONNECTOR OF FAN MOTOR

5. CONNECT NEGATIVE CABLE TO BATTERY

HEATER BLOWER RESISTOR

INSPECTION OF RESISTOR

INSPECT RESISTOR RESISTANCE
Check that there is continuity between terminals 4 and 6.
If there is no continuity, replace the resistor.

RELAYS

INSPECTION OF RELAYS

1. REMOVE RELAYS
