Test B: Power Windows Completely Inoperative
- Check Window Operation - Operate passenger windows from driver's master power window switch. If windows operate, go to TEST C: ONE POWER WINDOW INOPERATIVE . If windows do not operate, go to next step.
- Check Light Blue/Black Wire - Disconnect driver door window switch connector. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and driver door window switch connector Light Blue/Black wire. If battery voltage exists, go to step 4). If battery voltage does not exist, go to next step.
- Check Light Blue/Black Wire For Open Or Short To Ground - Disconnect instrument panel fuse block 27-pin connector C247. Using an ohmmeter, check resistance between ground and instrument panel fuse block connector C247 terminal No. 23 (Light Blue/Black wire). See Figure . If resistance is 10 k/ohms or less, repair short to ground in Light Blue/Black wire. Retest system operation. If resistance is more than 10 k/ohms, repair open in Light Blue/Black wire. Retest system operation.
- Check Ground Circuit - Using an ohmmeter, check resistance between ground and driver door window switch connector Black wire terminal. If resistance is 5 ohms or less, replace window switch and retest system operation. If resistance is more than 5 ohms, repair open in Black wire and retest system operation.
