2
•
Disconnect climate control unit connector
(24-pin) and air mix actuator connector.
•
Is there open circuit between following
terminals of climate control unit connector
(24-pin) and air mix actuator connector?
— 1B—B
— 1U—C
— 1I—A
Yes
Repair wiring harness.
No
Go to next step.
3
•
Is there short circuit to ground between
terminal 1U of climate control unit connector
(24-pin) and terminal C of air mix actuator
connector?
Yes
Repair wiring harness.
No
This system is normal at present. (Erase the past failure
from memory.)
