- A faulty brake light switch can prevent you from shifting out of Park.
- Symptoms include brake lights not working, staying on, or cruise control failure.
- Check for recalls on 2017 models before purchasing a replacement part.
- Replacement is a simple DIY task that takes less than 30 minutes.
Is Your Grand Caravan's Brake Light Switch Failing?
A faulty brake light switch on a 2012-2020 Dodge Grand Caravan can cause problems that seem unrelated at first. Because the switch communicates with multiple vehicle systems, its failure can lead to brake lights that don't work, stay on constantly, or prevent you from shifting out of park. These symptoms can be a major safety issue or simply leave you stranded. Understanding the signs is key to a quick diagnosis and repair.
Recall Notice for 2017 Models
Chrysler issued a recall (number U09) for certain 2017 Dodge Grand Caravan models due to malfunctioning brake switches. These switches could fail, causing the brake lights to stay on or allowing the vehicle to be shifted out of Park without the brake pedal being pressed. Owners of affected vehicles can get a free replacement switch from a Dodge dealer. It is wise to check if your VIN is part of this recall before purchasing a new part.
Symptoms of a Bad Brake Light Switch
- Brake Lights Not Working: The most obvious symptom is when your brake lights do not illuminate when you press the pedal. This is a serious safety hazard.
- Brake Lights Stay On: The switch can fail in the 'on' position, leaving your brake lights constantly illuminated and draining your battery.
- Cannot Shift Out of Park: The switch is part of the shift interlock safety system. If it fails, it won't send the signal that your foot is on the brake, leaving your gear selector stuck in Park.
- Cruise Control Issues: The cruise control system relies on the brake switch to disengage. A faulty switch might prevent the cruise control from setting or cause it to turn off unexpectedly.
- Warning Lights: A bad brake light switch can sometimes trigger the ABS or Electronic Stability Control (ESC) warning lights on your dashboard.
Choosing the Right Aftermarket Switch
When replacing the brake light switch, you have several options. While the Mopar OEM part is a direct-fit benchmark, quality aftermarket brands offer a reliable and more affordable alternative.
- OEM (Mopar): The original part (Part No. 4671336AD) is the standard for fit and function. It's the safest bet for guaranteed compatibility but comes at a higher price.
- Premium Aftermarket (Standard Ignition, Vemo): Brands like Standard Ignition are well-regarded for producing quality electronic components that often meet or exceed OEM specifications. They are a solid choice for a long-lasting repair.
- Value Aftermarket (Dorman, Crown Automotive): Dorman is known for creating direct replacement parts that are widely available and affordable. While some mechanics have mixed feelings about aftermarket brands, Dorman often provides a cost-effective solution that works well for common repairs like this. Crown Automotive is another option in this tier.
| Part Type | Estimated Cost |
|---|---|
| New OEM (Mopar) | $40 - $60 |
| New Aftermarket | $21 - $70 |
| Shop Labor | $80 - $140 |
Easy DIY Replacement
Replacing the brake light switch is a simple job for most DIYers. The switch is located above the brake pedal. It typically unplugs and twists out of its bracket. No special calibration is usually needed, but it's important not to tamper with the plunger on the new switch before installation. The entire process can often be completed in under 30 minutes with basic tools.
Frequently Asked Questions
Can I drive my Grand Caravan with a bad brake light switch?
It is not recommended. If your brake lights are not working, it is a major safety risk. If you are stuck in Park, you won't be able to drive at all. If the lights are stuck on, your battery will drain. You should get the switch replaced as soon as possible.
Why are my ABS and ESC lights on?
The stability control (ESC) and anti-lock brake (ABS) systems use the brake switch signal to know when you are braking. If the signal is faulty or missing, the computer can get confused and may disable these safety systems, turning on the warning lights.
Is a brake light switch the same as a brake pressure sensor?
No. The brake light switch is a simple mechanical switch activated by the movement of the brake pedal itself. A brake pressure sensor measures the hydraulic pressure within the brake lines and is a more complex electronic component.
How do I know it's the switch and not a fuse or bulb?
If all of your brake lights fail at once, the switch is a likely suspect. If only one light is out, it's probably a bulb. You should also check the brake light fuse in the fuse box under the hood before replacing the switch. If the fuse is good and all bulbs are out, the switch is the most probable cause.
