Subaru Legacy BN/BS (2015-2019) Service Manual / Hvac system (heater ventilator and a c) / Air mix door actuator / Inspection

1. ACTUATOR LINK

1. Visually check the operating range of the link, and remove the foreign matter if any.

2. Operate the temperature control switch, and check that the link operates normally.

3. If it does not operate normally as the result of inspection, perform a unit inspection of motor - actuator mix.

2. CHECK ACTUATOR OPERATION

1. Check the actuator operation when battery voltage is applied between the connector terminals.

CAUTION:

Disconnect the battery immediately after the actuator stops operation. Otherwise, the motor may be damaged.

Terminal No.	Inspection conditions	Operating position
6 (+) — 7 (−)	Connect battery to the terminals	• Driver’s seat: COOL • Passenger’s seat: HOT
7 (+) — 6 (−)	Connect battery to the terminals	• Driver’s seat: HOT • Passenger’s seat: COOL

2. Measure the resistance between connector terminals.

Preparation tool:

Circuit tester

Terminal No.	Inspection conditions	Operating position
1 — 3	Always	4.2 — 7.8 -

3. Connect the connector, turn the ignition switch to ON, and check the voltage between actuator terminals.

• Driver’s seat

Terminal No.	Inspection conditions	Operating position
5 (+) — 3 (−)	HOT	Approx. 1 V
5 (+) — 3 (−)	COOL	Approx. 4 V

• Passenger’s seat

Terminal No.	Inspection conditions	Operating position
5 (+) — 1 (−)	HOT	Approx. 1 V
5 (+) — 1 (−)	COOL	Approx. 4 V

4. Replace the motor - actuator mix if it is found defective as a result of inspection.

Removal
