Where is the brake light switch located on a 1995 GMC Safari Van?

On a 1995 GMC Safari van, the brake light switch is typically located on the brake pedal assembly itself. It's a small switch that's activated when you press the brake pedal. You'll likely find it near the top of the brake pedal, often attached to the pedal arm or a bracket very close to the pedal.

To locate it precisely, you'll probably need to look under the dashboard, above the brake pedal. You may need to remove some trim pieces to gain better access. A flashlight and possibly a small mirror will help. Consult a repair manual for your specific vehicle year and model for detailed diagrams and instructions. A Haynes or Chilton manual would be very helpful in this case.
