7D-20 AUTOMATIC CONTROL HVAC SYSTEM
Step
Repair the faulty circuit between the wiring connector of the blower
8 relay, wiring, blower motor, connector C203, C107.
Is the repair complete?
Measure voltage between terminal 30 of the blower relay and ground.
9
Is the voltage within the specified value?
1. Repair the circuit between terminal 86 of the blower relay and fuse
SB7 in the I/P fuse block.
2. Repair the wiring connector of the blower relay, wiring, blower
10
motor, connector C203, C107.
Is the repair complete?
1. Turn the ignition switch to OFF.
2. Using an ohmmeter, measure the resistance between terminal 85 of
11
the blower relay and ground.
Does the measured resistance indicate 0 Ω?

12
and ground G101.
Is the repair complete?
Replace the blower motor relay.
13
Is the repair complete?
Measure the resistance of the blower motor.
14
Does the measured resistance indicate 0.5 Ω?
Replace the blower motor.
15
Is the repair complete?
Measure the open or short of the circuit between terminal 1 of the
blower connector and terminal 30 of the blower high relay and terminal
16
6 of the power transistor.
Is there any open or short circuit?
Repair the problem in the circuit.
17
Is the repair complete?
Measure the resistance of the circuit from terminal 3 of the power
transistor connector and ground.
18
Does the measured resistance indicate 0 Ω?
Replace the controller.
19
Is the repair complete?
1. Repair the faulty circuit from terminal 3 of the power transistor
connector and terminal 87 of the high blower relay to ground.
20
2. Repair the faulty in the wiring, connector, C109, C209, C104 or
ground G104.
