HEATING, VENTILATION AND AIR CONDITIONING
DESCRIPTION
E6DBF81F
The mode control actuator is located at the heater unit.
It adjusts position of mode door by operating mode con-
trol actuator based on signal of A/C control unit. Pressing
mode select switch makes the mode control actuator shift
in order of vent→ B/L → floor → mix.
INSPECTION
EBFACAE1
1.
Ignition "OFF"
2.
Disconnect the connector of mode control actuator.
3.
Verify that the mode control actuator operates to the
defrost mode when connecting 12V to the terminal 3

It will feedback current position of actuator to controls.
6.
If the measured voltage is not specification, substitute
with a known-good mode control actuator and check
for proper operation.
7.
If the problem is corrected, replace the mode control
actuator.
