Test C: One Power Window Inoperative

NOTE: After making any repair, repeat Generic Electronic Module (GEM) self-test using NGS tester.
  1. Determine inoperative window. Test master window control switch and inoperative window switch. See MASTER WINDOW CONTROL SWITCH  and SINGLE SWITCH  under COMPONENT TESTS. If both switches are okay, reinstall switches and go to next step. If switch is defective, replace appropriate switch.
  2. Disconnect inoperative window motor harness connector. Connect a test light or voltmeter between suspect window motor harness connector terminals. Turn ignition switch to RUN position and operate master window control switch up and down for inoperative window. If battery voltage does not exist, go to next step. If battery voltage exists, ensure window tracks and mechanisms are not causing window to bind and repair if necessary. If window is not binding, replace window motor.
  3. Remove single window switch for inoperative window. Check resistance of circuits between inoperative window motor and single switch. For wire color identification, see WIRING DIAGRAMS  . If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in appropriate circuit.
  4. Remove master window control switch. Check resistance of circuits between single switch for inoperative window and master window control switch. For wire color identification, see WIRING DIAGRAMS  . If resistance is 5 ohms or less, replace single switch. If resistance is greater than 5 ohms, repair open in appropriate circuit.
