Standard Ignition NS-50 neutral safety switch for the 1990 Pontiac Grand Prix and other vehicles restores the neutral safety function. This electrically operated direct-fit switch replaces a damaged OE unit.
A car that will not crank in park or neutral, or that cranks while in gear, can mean the neutral safety switch is wearing out. A weak battery, a worn starter or shift linkage that is out of adjustment can be behind the same signs, so find the cause before buying a switch. Each car takes a single switch.
This neutral safety switch for the 1990 Pontiac Grand Prix also fits the 1990 Chevrolet Lumina and the 1990 Oldsmobile Cutlass Supreme. It is made to OE spec for fit, form and function.
