If battery voltage does not exist, go to next step.
  3. Repair open or high resistance in Red wire between left rear window regulator motor connector terminal No. 1 and splice S272. See WIRING DIAGRAMS  . After repair is complete, go to step  13 .
  4. Using DVOM connected to ground, measure resistance of Black wire at left rear window regulator motor connector terminal No. 4. If resistance is less than 5 ohms, go to step  6 . If resistance is 5 ohms or more, go to next step.
  5. Repair open or high resistance in Black wire between left rear window regulator motor connector terminal No. 4 and splice S700. See WIRING DIAGRAMS  . After repair is complete, go to step  13 .
  6. Turn ignition switch to RUN position. Disconnect left rear window switch connector. Using DVOM connected to ground, measure voltage at left rear window switch connector terminal No. 7 (White wire). If battery voltage exists, go to step  8 . If battery voltage does not exist, go to next step.
  7. Repair open or high resistance in White wire between left rear window switch connector terminal No. 7 and splice S273. See WIRING DIAGRAMS  . After repair is complete, go to step  13 .
  8. Connect left rear window switch. Press left rear window switch to UP position. Using DVOM connected to ground, measure voltage at left rear window regulator motor connector terminal No. 2 (Gray/Green wire). If battery voltage exists, go to step  10 . If battery voltage does not exist, go to next step.
  9. Check for open or high resistance in Gray/Green wire between left rear window switch connector terminal No. 1 and left rear window regulator motor connector terminal No. 2. See WIRING DIAGRAMS  . Repair as necessary. If Gray/Green wire is okay, replace left rear window switch. See WINDOW SWITCH  under REMOVAL & INSTALLATION. After repair is complete, go to step  13 .
  10. Press left rear window switch to DOWN position. Using DVOM connected to ground, measure voltage at left rear window regulator motor connector terminal No. 3 (Blue/Red wire). If battery voltage exists, go to step  12 . If battery voltage does not exist, go to next step.
  11. Check for open or high resistance in Blue/Red wire between left rear window switch connector terminal No. 9 and left rear window regulator motor connector terminal No. 3. See WIRING DIAGRAMS  . Repair as necessary. If Blue/Red wire is okay, replace left rear window switch. See WINDOW SWITCH  under REMOVAL & INSTALLATION. After repair is complete, go to step  13 .
  12. Replace left rear window regulator motor. See WINDOW REGULATOR & MOTOR  under REMOVAL & INSTALLATION. After repair is complete, go to next step.
  13. Connect all connectors and components that were disconnected. Verify left rear window operates properly. If left rear window does not operate properly, go to step  1 .
