2INSPECT AIRMIX DAMPER SERVO SUB±ASSY
(a)Remove the air mix damper servo sub±assy.
(b)Connect the positive (+) lead from the battery to terminal
MAX HOT and negative (±) lead to terminal MAX COOL,
then check that the lever turns to ºHOTº side smoothly.
(c)Connect the positive (+) lead from the battery to terminal MAX COOL and negative (±) lead to terminal MAX HOT,
then check that the lever turns to ºCOOLº side smoothly.

DTC 43 AIR OUTLET DAMPER CONTROL
SERVOMOTOR CIRCUIT
CIRCUIT DESCRIPTION
This circuit turns the servomotor and changes each mode damper position by the signals from the A/C ampli-
fier assy. When the AUTO switch is on, the A/C amplifier changes the mode automatically between ºFACEº,
ºBI±LEVELº, ºFOOTº and ºFOOT/DEFº according to the temperature setting.
DTC No.Detection ItemTrouble Area
43Air mode damper position sensor value does not change even
if A/C amplifier operated mode damper control servomotor.
