Preliminary Inspection

Check power window system circuit breaker located in instrument panel fuse block. See COMPONENT LOCATIONS . Ensure grounds are clean and tight. See WIRING DIAGRAMS . If only master window switch operates windows, ensure lock-out is not engaged (4-door).
Check for broken or partially broken wire inside insulation which would cause system failure but prove good in continuity/voltage check. Ensure proper installation of aftermarket electronic equipment that may affect integrity of other systems. If problem still exists, repair by symptom. See SYMPTOM INDEX table under SYMPTOM TESTS.
