Subaru Outback: Relay and Fuse

A: LOCATION

Subaru Outback. HVAC System (Heater, Ventilator and A/C)

NOTE: For other related fuses, refer to the wiring diagram. <Ref. to WI-15, Power Supply Circuit.>

B: INSPECTION

1. CHECK FUSE.

1) Remove the fuse and inspect visually.

2) If the fuse is blown out, replace the fuse.

NOTE: If the fuse is blown again, check the system wiring harness.

2. CHECK RELAY

1) Measure the resistance between blower motor relay terminals.

2) Replace the blower motor relay if the inspection result is not within the standard value.

Compressor Oil

A: PROCEDURE

NOTE: Before making repairs, perform the oil return operation to return the compressor oil in circulation with the refrigerant to the compressor.

1) Increase the engine to 1,500 rpm.

2) Turn the A/C switch to ON.

3) Set the temperature control switch or dial to LO (MAX COOL).

4) Turn the FRESH/RECIRC switch to RECIRC position.

5) Turn the airflow adjustment switch or dial to HI (MAX).

6) Leave in this condition for 10 minutes.

B: REPLACEMENT

NOTE:
