Preliminary Inspection
Check PWR WDO (25-amp) circuit breaker. For circuit breaker location, see Fig 1 . Ensure grounds are clean and tight. If only master window switch assembly 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 is found, repair as necessary. If no problem is found, perform self-diagnosis. See SELF-DIAGNOSTIC SYSTEM .
