Test A: All Power Windows Inoperative: Notes
NOTE:
Vehicle is equipped with express up, torque sensitive front door windows. When battery or power has been removed from either front door module, programming procedure will need to be performed, once power has been restored. See WINDOW MOTOR - EXPRESS MODE
under PROGRAMMING.
- If door systems diagnostic system check has been performed, go to next step. If door systems diagnostic system check has not been performed, perform door systems diagnostic system check. See DOOR SYSTEMS DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM.
- Turn ignition switch to RUN position. Attempt to operate power windows from both Driver Door Switch Assembly (DDSA), and passenger side window switches. If all windows are inoperative, go to next step. If any window operates, problem may be intermittent. For aid in diagnosing intermittents, see PRELIMINARY INSPECTION under TROUBLE SHOOTING.
- Remove PWR WDO circuit breaker (30-amp) from rear fuse block. Rear fuse block is located below left side of rear passenger seat. Using test light connected to ground, probe battery supply voltage socket of PWR WDO circuit breaker. See WIRING DIAGRAMS . If test light illuminates, go to next step. If test light does not illuminate, go to step 9 .
- Connect a test light between PWR WDO circuit breaker sockets. If test light does not illuminate, leave test light connected, and go to next step. If test light illuminates, go to step 6 .
- Operate any window switch, while observing test light. If test light does not illuminate, go to step 8 . If test light illuminates, go to step 13 .
- Gain access to door modules. Door modules are located behind respective door trim panel. Disconnect door module harness connectors one at a time, while observing test light. If test light goes out after any module is disconnected, go to next step. If test light remains illuminated after all modules are disconnected, go to step 10 .
- Check for poor, loose or corroded terminals in suspect door module harness connector. If problem does not exist, go to step 11 . If problem exists, repair as necessary. After repair, go to step 14 .
- Check for poor, loose or corroded terminals in rear fuse block sockets. If problem does not exist, go to step 12 . If problem exists, repair as necessary. After repair, go to step 14 .
- Repair open in battery supply circuit (Black wire) between battery and rear fuse block. See POWER DISTRIBUTION article in WIRING DIAGRAMS. After repair, go to step 14 .
- Repair short to ground in Orange wire between rear fuse block and suspect door module harness connector C5 terminal "A". See Fig 1 . See WIRING DIAGRAMS . After repair, go to step 14 .
- Replace suspect door module. See DOOR MODULE under REMOVAL & INSTALLATION. Perform window motor programming. See WINDOW MOTOR - EXPRESS MODE under PROGRAMMING. After repair, go to step 14 .
- Replace rear fuse block. After repair, go to step 14 .
- Replace PWR WDO circuit breaker. After repair, go to next step.
- Operate system to verify repair. If system operates normally, testing is complete. If system does not operate normally, go to step 2 .
