Symptoms of a Failing Brake Light Switch
A bad brake light switch on your MPV can cause several obvious problems. Because this part is essential for safety, you should address these symptoms immediately.
Most Common & Severe Symptoms
- Brake Lights Don't Work: This is the most dangerous symptom. The switch fails to complete the electrical circuit, and your brake lights will not turn on at all.
- Brake Lights Stay On: The switch can get stuck in the 'on' position, causing the brake lights to remain illuminated even when your foot is off the pedal. This can drain your battery and confuse other drivers.
Other Potential Symptoms
- Cruise Control Malfunctions: Your cruise control might not engage, or it may not turn off when you press the brake pedal.
- ABS or Traction Control Warning Lights: On some vehicles, a faulty brake switch can cause the ABS or traction control warning lights to appear on your dashboard.
Pro Tip: Before replacing the switch, always check the simple things first. Make sure the brake light bulbs are not burned out and check the brake light fuse in the fuse panel.
Choosing the Right Aftermarket Brake Light Switch
For a vehicle like the 1989-1999 MPV, an original Mazda (OEM) part may be hard to find or expensive. Aftermarket parts are widely available and offer excellent value. The key is choosing a brand known for quality and proper fitment.
For a simple switch, the technology is not complex. The most important factors are durable materials and correct electrical connections. Reputable aftermarket brands design their parts to match the original's form, fit, and function.

Frequently Asked Questions (FAQ)
Where is the brake light switch located on a 1989-1999 Mazda MPV?
The brake light switch is located up under the driver's side dashboard, mounted on a bracket near the top of the brake pedal arm. You will need to look up from the floor to see it.
Can I replace the brake light switch myself?
Yes, this is a very DIY-friendly repair. It typically requires no special tools—just unplugging the electrical connector and unscrewing or unclipping the old switch. The most difficult part is the awkward position you have to be in to reach it.
My brake lights are stuck on. Could it be something other than the switch?
Yes. On the brake pedal arm, there is a small plastic or rubber stopper that presses the switch's plunger. These stoppers can become brittle with age and break. If the stopper is missing, the switch's plunger will extend as if the brake is being pressed, keeping the lights on. Check for a broken stopper on the floor mat or a hole in the pedal bracket where it should be.
Are there any recalls for the brake light switch on the 1989-1999 MPV?
Searches of the NHTSA database did not show any specific recalls for the brake light switch on the 1989-1999 Mazda MPV. However, a recall was issued for the ignition switch on 1989-1998 models, which could cause various electrical problems.
Technical Specifications
Typically a 2-terminal, plunger-style switch mounted to the brake pedal bracket.
