  11. Measure resistance between ground and Yellow/Red wire terminal at right rear window motor harness connector. If resistance is greater than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Yellow/Red wire.
  12. Measure resistance in Yellow/Red wire between right rear window motor harness connector and terminal No. 5 at right rear window switch harness connector C806. See Fig 1 . If resistance is 5 ohms or less, replace right rear window switch. If resistance is greater than 5 ohms, repair open in Yellow/Red wire.
  13. Measure resistance between ground and Yellow/Red wire terminal at inoperative window motor harness connector. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, replace driver's door master window switch.
  14. Measure voltage at Red/Yellow wire terminal at inoperative window motor harness connector while pressing driver's door master window switch to appropriate window UP position. If battery voltage does not exist, go to next step for left rear window or go to step  20 for right rear window. If battery voltage exists, go to step  25 .
  15. Disconnect left rear window switch harness connector C706. Turn ignition switch to RUN position. Measure voltage at terminal No. 4 (Gray/Orange wire) at left rear window switch harness connector C706 while pressing driver's door master window switch to left rear window UP position. See Fig 1 . If battery voltage does not exist, go to next step. If battery voltage exists, go to step  18 .
  16. Disconnect driver's door master window switch harness connector C503. Measure resistance between ground and terminal No. 4 (Gray/Orange wire) at left rear window switch harness connector C706. If resistance is greater than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Gray/Orange wire.
  17. Measure resistance in Gray/Orange wire between terminal No. 4 at left rear window switch harness connector C706 and terminal No. 17 at driver's door master window switch harness connector C503. See Figure and Fig 1 . If resistance is 5 ohms or less, replace driver's door master window switch. If resistance is greater than 5 ohms, repair open in Gray/Orange wire.
  18. Measure resistance between ground and Red/Yellow wire terminal at left rear window motor harness connector. If resistance is greater than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair short to ground in Red/Yellow wire.
