Power Windows: Other Subaru Forester SF

Forester, Legacy & Legacy Outback

1. Remove power window relay. Check continuity between relay terminals. (Scheme 9) Continuity should be present between terminals No. 1 and 3. Continuity should not be present between terminals No. 2 and 4. If continuity is as specified, go to next step. If continuity is not as specified, replace power window relay.
2. Apply battery voltage between terminals No. 1 and 3. Continuity should now be present between terminals No. 2 and 4. If continuity is as specified, relay is okay at this time. If continuity is not as specified, replace power window relay.

Impreza

1. Remove power window relay. Check continuity between relay terminals. (Scheme 10) Continuity should be present between terminals No. 1 and 2. Continuity should not be present between terminals No. 3 and 4. If continuity is as specified, go to next step. If continuity is not as specified, replace power window relay.
2. Apply battery voltage between terminals No. 1 and 2. Continuity should now be present between terminals No. 3 and 4. If continuity is as specified, relay is okay at this time. If continuity is not as specified, replace power window relay.

SYSTEM TESTS

1. Check Fuse & Power Supply Check appropriate power window fuse in fuse panel. If fuse is okay, go to next step. If fuse is blown, repair short to ground in circuit between fuse box and power window relay. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) .
2. Check Power Window Relay Remove and check power window relay. See «POWER WINDOW RELAY TEST»(ref-124098-S22873904632001092800000) under COMPONENT TESTS. If power window relay is okay, go to next step. If power window relay is defective, replace relay.
3. Check Relay Ground Check resistance between ground and power window relay harness connector terminal No. 3. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) . If resistance is 10 ohms or less, go to next step. If resistance is not 10 ohms or less, repair open in circuit.
4. Check Relay Power Check voltage between ground and power window relay harness connector terminal No. 1. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) . If battery voltage is present, go to next step. If battery voltage is not present, repair open in circuit.
5. Check Black/Yellow Wire For Open Disconnect power window main switch harness connector. Check resistance in circuit between power window main switch and power window relay harness connectors. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) . If resistance is 10 ohms or less, go to next step. If resistance is not 10 ohms or less, repair open in circuit.
6. Check Power Window Main Switch Remove power window main switch and disconnect harness connector. Check power window main switch. See «POWER WINDOW MAIN SWITCH TEST»(ref-124098-S13154025122001092800000) under COMPONENT TESTS. If power window main switch is okay, go to next step. If power window main switch is defective, replace power window main switch.
7. Check Power Window Main Switch Ground Check resistance between ground and power window main switch harness connector terminal No. 12. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) . If resistance is 10 ohms or less, go to next step. If resistance is not 10 ohms or less, repair open in circuit.
8. Check Suspected Door Motor Disconnect suspected power window motor harness connector. Briefly apply battery voltage across motor terminals. Ensure motor operates smoothly. Reverse polarity and ensure that motor operates smoothly in opposite direction. If motor operates as described, go to next step. If motor does not operate as described, replace defective motor.
9. Check Harness Check resistance in wires between power window main switch harness connector and inoperative window motor harness connector. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) . If resistance is greater than 10 ohms in either wire, go to next step. If resistance is not greater than 10 ohms in both wires, go to step 11).
10. Check Sub-Switch Remove sub-switch of inoperative window. Check sub-switch. See «POWER WINDOW SUB-SWITCH TEST»(ref-124098-S24437944892001092800000) under COMPONENT TESTS. If sub-switch is okay, repair open in appropriate wire between power window main switch and inoperative window motor. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) . If sub-switch is defective, replace sub-switch.
11. Check Sub-Switch Power Supply Check voltage between ground and affected sub-switch harness connector terminal No. 5. See «WIRING DIAGRAMS»(ref-124098-S25506789722001092800000) . If battery voltage is present, system is okay. Check for loose connections. If battery voltage is not present, repair open in circuit between sub-switch and power window relay.
