Test E: Right Rear Window Does Not Operate

  1. Check Driver Door Master Window Switch  - Turn ignition off. Remove and disconnect driver door master window switch. Turn ignition switch to RUN position. Connect a jumper wire between driver door master window switch 16-pin connector C74a terminal No. 5 (White wire) and driver door master window switch 4-pin connector C74b terminal No. 3 (Black wire). See Figure and Figure . Connect another jumper wire between driver door master window switch 16-pin connector C74a terminal No. 6 (Yellow wire) and driver door master window switch 4-pin connector C74b terminal No. 2 (Violet/Blue wire). If right rear window does not go down, go to next step. If right rear window goes down, replace driver door master window switch and retest system operation.
  2. Check White & White/Blue Wire For Open Or Short To Ground  - Turn ignition off. Disconnect right rear door window switch connector. Using an ohmmeter, check resistance between driver door master window switch connector C74a terminal No. 5 (White wire) and right rear door window switch connector C490 terminal No. 6 (White/Blue wire). See Figure and Figure . Check resistance between ground and driver door master window switch connector C74a terminal No. 5 (White wire). If resistance is less than 5 ohms between connectors and more than 10 k/ohms between connector and ground, go to next step. If resistance is 5 ohms or more between connectors and 10 k/ohms or less between connector and ground, repair White and/or White/Blue wire and retest system operation.
  3. Check Yellow & Yellow/Blue Wire For Open Or Short To Ground  - Using an ohmmeter, check resistance between driver door master window switch connector C74a terminal No. 6 (Yellow wire) and right rear door window switch connector C490 terminal No. 3 (Yellow/Blue wire). See Figure and Figure . Check resistance between ground and driver door master window switch connector C74a terminal No. 6 (Yellow wire). If resistance is less than 5 ohms between connectors and more than 10 k/ohms between connector and ground, go to next step. If resistance is 5 ohms or more between connectors and 10 k/ohms or less between connector and ground, repair Yellow and/or Yellow/Blue wire and retest system operation.
  4. Check Violet Wire For Voltage  - Turn ignition off. Reconnect driver door master window switch connectors. Turn ignition switch to RUN position. Ensure driver door master window switch lock-out is off. Using a voltmeter, check voltage between ground and right rear door window switch connector C490 terminal No. 2 (Violet wire). See Figure . If reading is more than 10 volts, go to next step. If reading is 10 volts or less, repair Violet and/or Violet/Yellow wire and retest system operation.
  5. Check Right Rear Door Window Switch  - Connect a jumper wire between right rear door window switch connector C490 terminals No. 1 (White/Red wire) and No. 6 (White/Blue wire). See Figure . Connect another jumper wire between right rear door window switch connector C490 terminals No. 7 (Yellow/Red wire) and No. 2 (Violet wire). If right rear window does not go down, go to next step. If right rear window goes down, replace right rear door window switch and retest system operation.
  6. Check White/Red Wire For Open Or Short To Ground  - Turn ignition off. Disconnect right rear door window motor connector. Using an ohmmeter, check resistance between right rear door window switch connector C490 terminal No. 1 (White/Red wire) and right rear door window motor connector terminal No. 2 (White/Red wire). See Figure . Check resistance between ground and right rear door window switch connector C490 terminal No. 1 (White/Red wire). If resistance is less than 5 ohms between connectors and more than 10 k/ohms between connector and ground, go to next step. If resistance is 5 ohms or more between connectors and 10 k/ohms or less between connector and ground, repair White/Red wire and retest system operation.
  7. Check Yellow/Red Wire For Open Or Short To Ground  - Using an ohmmeter, check resistance between right rear door window switch connector C490 terminal No. 7 (Yellow/Red wire) and right rear door window motor connector terminal No. 1 (Yellow/Red wire). See Figure . Check resistance between ground and right rear door window switch connector C490 terminal No. 7 (Yellow/Red wire). If resistance is less than 5 ohms between connectors and more than 10 k/ohms between connector and ground, replace right rear window motor and retest system operation. If resistance is 5 ohms or more between connectors and 10 k/ohms or less between connector and ground, repair Yellow/Red wire and retest system operation.
