Test H: Left Front & Left Rear Windows Are Inoperative

  1. Check Switch Input  - Turn ignition switch to RUN position. Using NGS tester, select and monitor DDM PIDs D_PW_SW and LRPW_SW. Press and release driver door window control switch left front and left rear window switch in the UP and DOWN position several times. If PID values agree with the switch position, go to next step. If PID values do not agree with the switch position, replace driver door module and retest system operation.
  2. Check Fuse  - Ensure transmission is in Park. Turn ignition off. Remove and check condition of engine compartment power distribution box maxi-fuse No. 5 (40-amp). If fuse is okay, go to next step. If fuse is open, replace fuse and retest system operation. If new fuse opens again, go to step 4).
  3. Check For Voltage To Fuse  - Using a voltmeter, check voltage between ground and engine compartment power distribution box maxi-fuse No. 5 (40-amp) input cavity. If voltage is more than 10 volts, repair open in Yellow/Light Green wire and retest system operation. If voltage is 10 volts or less, replace engine compartment power distribution box and retest system operation.
  4. Check Yellow/Light Green Wire For Short To Ground  - Remove engine compartment power distribution box fuse No. 9 (40-amp). Remove instrument panel fuse block fuse No. 41 (20-amp). Disconnect left rear window control switch 4-pin square connector C709. Using an ohmmeter, check resistance between ground and engine compartment power distribution box maxi-fuse No. 5 (40-amp) output cavity. If resistance is more 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 and retest system operation.
  5. Check Left Rear Window Control Switch  - Check 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 not okay, replace switch and retest system operation.
  6. Check Yellow/Light Blue & Gray/Orange Wire For Voltage  - Using a voltmeter, check voltage between ground and left rear window control switch 4-pin flat connector C711 Yellow/Light Blue wire terminal. Check voltage between ground and left rear window control switch 4-pin flat connector C711 Gray/Orange wire terminal. If either voltage reading is more than 10 volts, repair Yellow/Light Blue and/or Gray/Orange wire for short to voltage and retest system operation. If both voltage readings are 10 volts or less, go to next step.
  7. Check Yellow/Light Blue & Gray/Orange Wire For Short To Ground  - Disconnect DDM 20-pin connector C523 (located in lower front corner of driver door). Using an ohmmeter, check resistance between ground and left rear window control switch 4-pin flat connector C711 Yellow/Light Blue wire terminal. Check resistance between ground and left rear window control switch 4-pin flat connector C711 Gray/Orange wire terminal. If both resistance readings are more than 10 k/ohms, go to next step. If either resistance reading is 10 k/ohms or less, repair short to ground in Yellow/Light Blue and/or Gray/Orange wire and retest system operation.
  8. Check Yellow/Black & Yellow/Light Blue Wire For Voltage  - Using a voltmeter, check voltage between ground and left rear window control switch 4-pin square connector C709 Yellow/Black wire terminal. Check voltage between ground and left rear window control switch 4-pin square connector C709 Yellow/Light Blue wire terminal. If both voltage readings are more than 10 volts, go to next step. If either voltage reading is 10 volts or less, go to step 10).
  9. Check Yellow/Black & Yellow/Light Blue Wire For Short To Voltage  - Disconnect left rear window motor connector C710. Using a voltmeter, check voltage between ground and left rear window control switch 4-pin square connector C709 Yellow/Black wire terminal. If voltage reading is more than 10 volts, repair short to voltage in Yellow/Black wire and retest system operation. If voltage reading is 10 volts or less, repair short to voltage in Yellow/Light Blue wire and retest system operation.
  10. Check Yellow/Black & Yellow/Light Blue Wire For Short To Ground  - Using an ohmmeter, check resistance between ground and left rear window control switch 4-pin square connector C709 Yellow/Black wire terminal. Check resistance between ground and left rear window control switch 4-pin square connector C709 Yellow/Light Blue wire terminal. If both resistance readings are 10 k/ohms or less, go to next step. If both resistance readings are more than 10 k/ohms, go to step 12).
  11. Check Yellow/Black & Yellow/Light Blue Wire For Short To Ground  - Disconnect left rear window motor connector C710. Using an ohmmeter, check resistance between ground and left rear window control switch 4-pin square connector C709 Yellow/Black wire terminal. Check resistance between ground and left rear window control switch 4-pin square connector C709 Yellow/Light Blue wire terminal. If both resistance readings are more than 10 k/ohms, replace left rear window motor and retest system operation. If either resistance reading is 10 k/ohms or less, repair short to ground in Yellow/Black and/or Yellow/Light Blue wire and retest system operation.
  12. Check Pink/Yellow & Red/Yellow Wire For Short To Voltage  - Disconnect DDM 4-pin connector C522 (located in lower front corner of driver door). Using a voltmeter, check voltage between ground and DDM 4-pin connector C522 terminal No. 1 (Pink/Yellow wire). Using a voltmeter, check voltage between ground and DDM 4-pin connector C522 terminal No. 2 (Red/Yellow wire). If either voltage reading is more than 10 volts, go to next step. If either reading is 10 volts or less, go to step 14).
  13. Check Pink/Yellow Wire For Short To Voltage  - Disconnect left front window motor connector C514. Using a voltmeter, check voltage between ground and DDM 4-pin connector C522 terminal No. 1 (Pink/Yellow wire). If voltage reading is more than 10 volts, repair Pink/Yellow wire for short to voltage and retest system operation. If voltage reading is 10 volts or less, repair Red/Yellow wire and retest system operation.
  14. Check Pink/Yellow & Red/Yellow Wire For Short To Ground  - Using an ohmmeter, check resistance between ground and DDM 4-pin connector C522 terminal No. 1 (Pink/Yellow wire). Check resistance between ground and DDM 4-pin connector C522 terminal No. 2 (Red/Yellow wire). If either resistance reading is 10 k/ohms or less, go to next step. If both resistance readings are more than 10 k/ohms, replace driver door module and retest system operation.
  15. Check Left Front Window Motor For Short To Ground  - Disconnect left front window motor connector C514. Using an ohmmeter, check resistance between ground and DDM 4-pin connector C522 terminal No. 1 (Pink/Yellow wire). Check resistance between ground and DDM 4-pin connector C522 terminal No. 2 (Red/Yellow wire). If both resistance readings are more than 10 k/ohms, replace left front window motor and retest system operation. If either resistance reading is 10 k/ohms or less, repair short to ground in Pink/Yellow and/or Red/Yellow wire and retest system operation.
