Is Your Caravan's Brake Light Switch Failing?
A bad brake light switch on a 2002-2007 Dodge Caravan can cause several confusing problems. Because this switch 🎬 Watch this overview of bad brake light switch symptoms and costs. communicates with multiple systems, its failure isn't always straightforward. Recognizing the signs early can save you from a potential safety hazard or a vehicle that won't shift out of park.
Common Symptoms of Failure:
- Brake Lights Don't Work: The most dangerous symptom. The switch fails to send a signal, and your brake lights never turn on.
- Brake Lights Stay On: The switch can fail in the 'on' position, leaving your brake lights illuminated constantly, which can drain your battery and confuse other drivers.
- Can't Shift Out of Park: Your Caravan has a safety feature called a shift interlock that requires the brake pedal to be pressed before you can move the shifter. A bad switch prevents the vehicle from knowing you're on the brake.
- Cruise Control Issues: The cruise control may not engage, or it might shut off unexpectedly while driving. This happens because the faulty switch might be sending an incorrect signal that the brakes are being applied.
- ABS or Traction Control Warning Lights: A faulty brake light switch can sometimes trigger warning lights on your dashboard as it confuses the vehicle's stability and braking systems.
An Important Note on Diagnosis
Before replacing the switch, always check the 20-amp brake light fuse in the under-hood fuse box first. Also, inspect 🎬 See how to locate the fuse and replace the switch. the brake light bulbs and the sockets in the tail light assemblies, as corrosion or melted contacts in the sockets are also a known issue on these vans.

For the 2002-2007 Dodge Caravan, the original Mopar switch has been superseded several times. The aftermarket offers several quality alternatives that meet or exceed original specifications. The key is choosing a reputable brand, as a cheap, poorly made switch can fail quickly.
Brand Tiers for Your Caravan:
- Standard Ignition (SMP): Often considered a top-tier aftermarket brand, Standard produces parts that are well-regarded for their durability and performance, often rivaling OEM quality. This is a solid choice for reliability.
- Rostra Powertrain: Rostra is a well-known manufacturer of various automotive electronic components, including cruise control systems and switches. They are generally seen as a reliable mid-to-high-tier option.
- Crown Automotive: Crown specializes in parts for Chrysler, Dodge, and Jeep vehicles. While they offer a wide range of components, their quality can sometimes be inconsistent depending on the specific part. For a critical safety item like a brake light switch, sticking with a brand known for electronic component quality like Standard or Rostra is often preferred by professional mechanics.
Installation Pro-Tip
The replacement switch for this Caravan is a one-time-use, self-adjusting part. It is critical that you DO NOT touch or move the small adjustment lever on the new switch before it is fully installed. The switch is installed with a 45-degree twist, and only after it is securely in place should you flip the lever to set the correct plunger depth. Reinstalling a used switch or adjusting a new one before installation will result in improper function.

Frequently Asked Questions
Is there a recall on the brake light switch for the 2002-2007 Dodge Caravan?
There have been no direct recalls from Dodge for the factory-installed brake light switch on these specific model years. However, there was a safety recall (NHTSA Campaign 16E001000) for certain aftermarket Duralast-branded stoplight switches made by Wells that fit these vans. This highlights the importance of using quality replacement parts.
Can I replace the brake light switch myself?
Yes, this is a very feasible DIY job for most owners. It requires working in the driver's footwell, which can be awkward, but no special tools are needed. The switch is removed and installed with a simple twist-and-lock motion. The entire process typically takes less than 30 minutes.
Why do my third brake light work but not the main ones?
On these Caravans, the brake light switch sends power directly to the third (center) brake light. Power for the main left and right brake lights is routed through the vehicle's main computer (Front Control Module or Body Control Module). If only the third light works, it confirms the switch is likely good and the problem may be with the module, wiring, or the tail light sockets themselves.
What is the OEM part number for the brake light switch?
The most current Mopar OEM part number is 4671336AD. It replaces previous versions like 4671336, 4671336AB, and 4671336AC.
