Diagnostic procedure

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