Preliminary Inspection
WARNING: This page is about a different car, the 2002 Pontiac Sunfire, 2002 Chevrolet Cavalier, 2001 Pontiac Sunfire, and 2001 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
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 .
