Test H: Both Left Side Windows Are Inoperative

NOTE: Left rear window control switch harness connector C711 is a flat 4-pin connector. Left rear window control switch harness connector C709 is a square 4-pin connector.
  1. Turn ignition switch to ON position. Using New Generation Star (NGS) tester, select and monitor Driver's Door Module (DDM) PIDs D_PW_SW and LRPW_SW. Press and release master window control switch left front and left rear window switch in up and down positions several times. If PID agrees with the switch position, go to next step. If PID does not agree with the switch position, replace DDM.
  2. Ensure transmission is in Park. Turn ignition switch to OFF position. Remove and inspect maxi-fuse No. 5 (40-amp) from battery junction box. If fuse is okay, go to next step. If fuse is blown, replace fuse and retest system operation. If new fuse blows, go to step  4 .
  3. Measure voltage between ground and input side of maxi-fuse No. 5 (40-amp) in battery junction box. If battery voltage exists, repair open in Yellow/Light Green wire. If battery voltage does not exist, replace battery junction box.
  4. Remove fuse No. 9 (40-amp) from battery junction box. Remove fuse No. 41 (20-amp) from central junction box. Disconnect left rear window control switch harness connector C709. Measure resistance between ground and output side of maxi-fuse No. 5 (40-amp) in battery junction box. 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/Light Green wire.
  5. Test left rear window control switch. See SINGLE SWITCHES  under COMPONENT TESTS. If left rear window control switch is okay, go to next step. If left rear window control switch is defective, replace switch.
  6. Measure voltage between ground Yellow/Light Blue wire terminal at left rear window control switch harness connector C711. Measure voltage between ground and Gray/Orange wire terminal at left rear window control switch harness connector C711. If voltage does not exist at all terminals, go to next step. If voltage exists at any terminal, repair short to voltage in Yellow/Light Blue and/or Gray/Orange wire.
  7. Disconnect DDM harness connector C523. Measure resistance between ground and Yellow/Light Blue wire terminal at left rear window control switch harness connector C711. Measure resistance between ground and Gray/Orange wire terminal at left rear window control switch harness connector C711. If all resistances are greater than 10 k/ohms, go to next step. If any resistance is 10 k/ohms or less, repair short to ground in Yellow/Light Blue and/or Gray/Orange wire.
  8. Measure voltage between ground and Yellow/Black wire terminal at left rear window control switch harness connector C709. Measure voltage between ground and Yellow/Light Blue wire terminal at left rear window control switch harness connector C709. If voltage exists at any terminal, go to next step. If voltage does not exist at all terminals, go to step  10 .
  9. Disconnect left rear window motor harness connector C710. Measure voltage between ground and Yellow/Black wire terminal at left rear window control switch harness connector C709. If voltage exists, repair short to voltage in Yellow/Black wire. If voltage does not exist, repair short to voltage in Yellow/Light Blue wire.
  10. Measure resistance between ground and Yellow/Black wire terminal at left rear window control switch harness connector C709. Measure resistance between ground and Yellow/Light Blue wire terminal at left rear window control switch harness connector C709. If any resistance is 10 k/ohms or less, go to next step. If all resistances are greater than 10 k/ohms, go to step  12 .
  11. Disconnect left rear window motor harness connector C710. Measure resistance between ground and Yellow/Black wire terminal at left rear window control switch harness connector C709. Measure resistance between ground and Yellow/Light Blue wire terminal at left rear window control switch harness connector C709. If all resistances are greater than 10 k/ohms, replace left rear window motor. If any resistance is 10 k/ohms or less, repair short to ground in Yellow/Black and/or Yellow/Light Blue wire.
  12. Disconnect DDM harness connector C522. Measure voltage between ground and terminal No. 1 (Pink/Yellow wire) at DDM harness connector C522. Measure voltage between ground and terminal No. 2 (Red/Yellow wire) at DDM harness connector C522. See Figure . If voltage exist at any terminal, go to next step. If voltage does not exist at all terminals, go to step  14 .
  13. Disconnect left front window motor harness connector C514. Measure voltage between ground and terminal No. 1 (Pink/Yellow wire) at DDM harness connector C522. If voltage exists, repair short to voltage in Pink/Yellow wire. If voltage does not exist, repair short to voltage in Red/Yellow wire.
  14. Measure resistance between ground and terminal No. 1 (Pink/Yellow wire) at DDM harness connector C522. Measure resistance between ground and terminal No. 2 (Red/Yellow wire) at DDM harness connector C522. If any resistance is 10 k/ohms or less, go to next step. If all resistances are greater than 10 k/ohms, replace DDM.
  15. Disconnect left front window motor harness connector C514. Measure resistance between ground and terminal No. 1 (Pink/Yellow wire) at DDM harness connector C522. Measure resistance between ground and terminal No. 2 (Red/Yellow wire) at DDM harness connector C522. If all resistances are greater than 10 k/ohms, replace left front window motor. If any resistance is 10 k/ohms or less, repair short to ground in Pink/Yellow and/or Red/Yellow wire.
