Diagnostic procedure

STEP	INSPECTION		ACTION
1	•  Disconnect the driver-side (passenger-side) front air mix actuator connector. •  Connect battery positive voltage to terminal F (or terminal G) and ground to terminal G (or terminal F) of driver-side (passenger-side) front air mix actuator connector. •  Does driver-side (passenger-side) front air mix actuator operate?	Yes	Connect driver-side (passenger-side) front air mix actuator connector, then go to Step 3.
		No	Go to the next step.
2	•  Remove driver-side (passenger-side) front air mix actuator. (See FRONT AIR MIX ACTUATOR REMOVAL/INSTALLATION.) •  Operate air mix link by hand. •  Does air mix link operate smoothly?	Yes	Replace driver-side (passenger-side) front air mix actuator.
		No	Replace air mix link and/or air mix crank.
3	•  Disconnect climate control unit connector (24-pin). •  Connect battery positive voltage to following terminal and ground to following terminal of front climate control unit connector (24-pin). Driver-side (L.H.D.) ―  1D (B+), 1A (GND) ―  1A (B+), 1D (GND) Passenger-side (R.H.D.) ―  1E (B+), 1C (GND) ―  1C (B+), 1E (GND) •  Does driver-side (passenger-side) front air mix actuator operate?	Yes	Inspect the connection of the front climate control unit connector.
		No	Repair wiring harness.
