DESCRIPTION
Power to the rear blower motor is supplied from the battery via the RR A/C relay.
The rear blower motor speed level varies between 0 and 31 based on the voltage difference measured between the terminals of the motor.
The voltage difference measured between the terminals of the rear blower motor changes in proportion to the control at the rear blower motor controller on the ground side.

(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
5 CHECK HARNESS AND CONNECTOR (REAR BLOWER MOTOR - REAR BLOWER MOTOR CONTROLLER)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance
6 CHECK HARNESS AND CONNECTOR (REAR BLOWER MOTOR CONTROLLER - A/C AMPLIFIER)
(a) Disconnect the connector from the A/C amplifier.
(b) Measure the resistance according to the value(s) in the table below.
7 INSPECT REAR BLOWER MOTOR CONTROLLER
(a) Disconnect the connector from the rear blower motor controller.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
(c) Connect the positive (+) lead to terminal 3 through a 12 V 3.4 W test bulb, and the negative (-) lead to terminal 1.
(d) Connect the three 1.5 V dry cell batteries' positive (+) lead to terminal 2, and the negative (-) lead to terminal 1.
Then check that the test bulb comes on.
OK: The test bulb comes on.
