DTC 19	Driver-side front air mix actuator (potentiometer) (past) (L.H.D.) Passenger-side front air mix actuator (potentiometer) (past) (R.H.D.)
POSSIBLE CAUSE	• Driver-side (passenger-side) front air mix actuator malfunction • Open circuit between driver-side (passenger-side) front air mix actuator and front climate control unit • Short circuit between driver-side (passenger-side) front air mix actuator and front climate control unit

Diagnostic Procedure

STEP	INSPECTION		ACTION
1	• Inspect driver-side (passenger-side) front air mix actuator. (See FRONT AIR MIX ACTUATOR INSPECTION.) • Is it okay?	Yes	Go to the next step.
1		No	Replace driver-side (passenger-side) front air mix actuator. (See FRONT AIR MIX ACTUATOR REMOVAL/INSTALLATION.)
2	• Disconnect front climate control unit connector (16-pin) and driver-side (passenger-side) front air mix actuator connector. • Is there open circuit between following terminals of front climate control unit connector (16-pin) and driver-side (passenger-side) front air mix actuator connector? Driver-side (L.H.D.) ― 2F—E ― 2B—A ― 2P—C Passenger-side (R.H.D.) ― 2G—E ― 2B—A ― 2P—C	Yes	Repair wiring harness.
2		No	Go to the next step.
3	• Is there short circuit to ground between following terminal of front climate control unit connector (16-pin) and driver-side (passenger-side) front air mix actuator connector? Driver-side (L.H.D.) ― 2F—E Passenger-side (R.H.D.) ― 2G—E	Yes	Repair wiring harness.
3		No	This system is normal at present. (Erase the past failure from memory.)
