Where is the neutral safety switch located for a 1994 Buick Century?

The neutral safety switch on a 1994 Buick Century is located on the transmission. More specifically, it's usually mounted on the side of the transmission, near where the shift linkage connects. It's a relatively small switch, and you might need to get underneath the car to see it clearly.

Because the exact location can vary slightly depending on the transmission type (automatic transmission, of course, is the only type that would have one), it's best to consult a repair manual specific to your 1994 Buick Century to get a precise diagram and location. A Chilton's or Haynes manual would be helpful. You could also search online for a diagram specific to your vehicle's transmission type (e.g., "1994 Buick Century 3800 Series II neutral safety switch location").
