DIAGNOSIS AND TESTING (CONTINUED)
CONDITIONS
DETAILS/RESULTS/ACTIONS
C14: CHECK THE CIRCUIT FOR HEATER BLOWER, SLOW SPEED
1 Measure the voltage between heater blower
switch, connector C72, pin 3, circuit 31S-CA30
(BK/WH), harness side and ground.
• Is battery voltage indicated?
 Yes
CHECK the heater blower switch; INSTALL
a new one if necessary. TEST the system
for normal operation.
 No
GO TO C15
C15: CHECK THE CIRCUIT FOR HEATER BLOWER, SLOW SPEED
1. 2.
Heater blower se-
ries resistor C90
3 Measure the resistance between heater blower
series resistor, connector C90, pin 3, circuit
31S-CA30 (BK/WH), harness side and heater
blower switch, connector C72, pin 3, circuit
31S-CA30 (BK/WH), harness side.
• Is the resistance less than 2 ohms?
 Yes
CHECK the heater blower series resistor,
INSTALL a new on if necessary. TEST the
system for normal operation.
 No
REPAIR the open circuit(s) between heater
blower series resistor and heater blower
switch by using the wiring diagrams. TEST
the system for normal operation.
PINPOINT TEST D: THE AIR RE-CIRCULATION FLAP IS INOPERATIVE
CONDITIONS DETAILS/RESULTS/ACTIONS
D1: CHECK THE FUSE F16
1. 2.
Fuse F16 (CJB)
• Is the fuse OK?
 Yes
GO TO D2
 No
INSTALL a new fuse F16 (30 A). If the fuse
blows again, REPAIR the short to ground of
the circuit(s) by using the wiring diagrams.
TEST the system for normal operation.
