Test D: Rear Quarter Glass Inoperative

  1. Check Power Window Operation  - Turn ignition switch to RUN position. Operate driver's door power window. If driver's door power window operates, go to next step. If driver's door power window does not operate, go to TEST B: POWER WINDOWS COMPLETELY INOPERATIVE  .
  2. Identify Inoperative Window  - Operate left rear quarter window. If left quarter window is inoperative, go to next step. If left quarter window is not inoperative, go to step 11).
  3. Check Power Supply To Left Rear Quarter Window Motor In Open Position  - Gain access to left rear quarter window motor connector C418. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and left rear quarter window motor connector C418 Brown wire terminal while pressing left rear quarter window control switch to OPEN position. If battery voltage is not present, go to next step. If battery voltage is present, go to step 7).
  4. Check Left Rear Quarter Window Switch  - Turn ignition off. Ensure left rear quarter window control switch is in NEUTRAL position. Using an ohmmeter, check resistance between ground and left rear quarter window motor connector C418 Brown wire terminal. If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, go to step 6).
    NOTE: Driver master window switch contains 2 separate 7-pin connectors. On connector C501, all 7 terminals are used. On connector C514, only 4 terminals are used.
  5. Check Brown Wire For Open  - Gain access to left rear quarter window switch. Disconnect rear quarter window switch 7-pin connector C514. Using an ohmmeter, check resistance between rear quarter window switch connector C514 terminal No. 5 (Brown wire) and left rear quarter window motor connector C418 Brown wire terminal. See Fig 1 .

  6. Check Brown Wire For Short To Ground  - Gain access to left rear quarter window switch. Disconnect rear quarter window switch 7-pin connector C514. Using an ohmmeter, check resistance between ground and left rear quarter window motor connector C418 Brown wire terminal. If resistance is 10 k/ohms or less, repair short to ground in Brown wire and retest system operation. If resistance is more than 10 k/ohms, replace window switch and retest system operation.
  7. Check Power Supply To Motor In Close Position  - Using a voltmeter, check voltage between ground and left rear quarter window motor connector C418 Brown/Yellow wire terminal while pressing left rear quarter window switch to CLOSED position. If battery voltage is not present, go to next step. If battery voltage is present, replace left rear quarter window motor and retest system operation.
  8. Check Left Rear Quarter Window Switch  - Turn ignition off. Ensure left rear quarter window switch is in NEUTRAL position. Using an ohmmeter, check resistance between ground and left rear quarter window motor connector C418 Brown/Yellow wire terminal. If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, go to step 10).
    NOTE: Driver master window switch contains 2 separate 7-pin connectors. On connector C501, all 7 terminals are used. On connector C514, only 4 terminals are used.
  9. Check Brown/Yellow Wire For Open  - Gain access to left rear quarter window switch. Disconnect rear quarter window switch 7-pin connector C514. Using an ohmmeter, check resistance between rear quarter window switch connector C514 terminal No. 4 (Brown/Yellow wire) and left rear quarter window motor connector C418 Brown/Yellow wire terminal. See Fig 1 . If resistance is 5 ohms or less, replace window switch and retest system operation. If resistance is more than 5 ohms, repair open in Brown/Yellow wire and retest system operation.
  10. Check Brown/Yellow For Short To Ground  - Gain access to left rear quarter window switch. Disconnect rear quarter window switch 7-pin connector C514. Using an ohmmeter, check resistance between ground and left rear quarter window motor connector C418 Brown/Yellow wire terminal. If resistance is 10 k/ohms or less, repair short to ground in Brown/Yellow wire and retest system operation. If resistance is more than 10 k/ohms, replace window switch and retest system operation.
  11. Check Power Supply To Right Rear Quarter Window Motor In Open Position  - Gain access to right rear quarter window motor connector C419. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and right rear quarter window motor connector C419 Yellow/Black wire terminal while pressing right rear quarter window switch to OPEN position. If battery voltage is not present, go to next step. If battery voltage is present, go to step 15).
  12. Check Right Rear Quarter Window Switch  - Turn ignition off. Ensure right rear quarter window switch is in NEUTRAL position. Using an ohmmeter, check resistance between ground and right rear quarter window motor connector C419 Yellow/Black wire terminal. If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, go to step 14).
    NOTE: Driver master window switch contains 2 separate 7-pin connectors. On connector C501, all 7 terminals are used. On connector C514, only 4 terminals are used.
  13. Check Yellow/Black Wire For Open  - Gain access to right rear quarter window switch. Disconnect rear quarter window switch 7-pin connector C514. Using an ohmmeter, check resistance between rear quarter window switch connector C514 terminal No. 7 (Yellow/Black wire) and right rear quarter window motor connector C419 Yellow/Black wire terminal. See Fig 1 . If resistance is 5 ohms or less, replace window switch and retest system operation. If resistance is more than 5 ohms, repair open in Yellow/Black wire and retest system operation.
  14. Check Yellow/Black Wire For Short To Ground  - Gain access to right rear quarter window switch. Disconnect rear quarter window switch 7-pin connector C514. Using an ohmmeter, check resistance between ground and right rear quarter window motor connector C419 Yellow/Black wire terminal. If resistance is 10 k/ohms or less, repair short to ground in Yellow/Black wire and retest system operation. If resistance is more than 10 k/ohms, replace window switch and retest system operation.
  15. Check Power Supply To Motor In Close Position  - Using a voltmeter, check voltage between ground and right rear quarter window motor connector C419 Yellow/Light Blue wire terminal while pressing right rear quarter window switch to CLOSED position. If battery voltage is not present, go to next step. If battery voltage is present, replace right rear quarter window motor and retest system operation.
  16. Check Right Rear Quarter Window Switch  - Turn ignition off. Ensure right rear quarter window switch is in NEUTRAL position. Using an ohmmeter, check resistance between ground and right rear quarter window motor connector C419 Yellow/Light Blue wire terminal. If resistance is more than 5 ohms, go to next step. If resistance is 5 ohms or less, go to step 18).
    NOTE: Driver master window switch contains 2 separate 7-pin connectors. On connector C501, all 7 terminals are used. On connector C514, only 4 terminals are used.
