Volvo C70 Brake Light Switch Guide (2006-2013)
Having brake light, cruise control, or shifter problems in your C70? The brake light switch is a likely culprit.
- A bad brake light switch can cause brake light failure, prevent the car from shifting out of Park, and disable cruise control.
- This is a critical safety component; if your brake lights are not working, the vehicle is not safe to drive.
- Replacement is a simple, DIY-friendly task that takes less than an hour for most owners.
- Cost-effective aftermarket switches are a reliable option for this repair; there is no significant benefit to using a more expensive OEM part.
Is Your Volvo C70 Brake Light Switch Failing?
A failing brake light switch on a 2006-2013 Volvo C70 can cause a surprising number of issues. Because it communicates with multiple vehicle systems, the symptoms aren't always straightforward. Understanding these signs can help you diagnose the problem quickly and avoid unnecessary repairs.
Common Symptoms of a Bad Switch
- Brake Lights Don't Work or Stay On: The most obvious sign is your brake lights not lighting up when you press the pedal, or staying illuminated even when your foot is off the brake. This is a serious safety issue.
- Cannot Shift Out of Park: The switch is tied to the shift interlock safety feature. If it fails, it won't send the signal that the brake is applied, preventing you from moving the gear selector out of Park.
- Cruise Control Issues: The cruise control system relies on the brake light switch to disengage. A faulty switch can prevent you from setting the cruise control or cause it to turn off unexpectedly while driving.
- ABS Warning Light: A malfunctioning switch can sometimes trigger the Anti-lock Braking System (ABS) warning light to appear on your dashboard.
Choosing a New Aftermarket Brake Light Switch
For a simple component like the brake light switch, an aftermarket part is a very reasonable and cost-effective choice for the C70. The original equipment (OEM) part offers no significant advantage in longevity or performance for this specific component, which tends to fail from simple mechanical wear. Aftermarket brands like Facet, Standard Ignition, Vemo, and VNE all produce switches that meet the required specifications.
There is little evidence from owner forums or mechanic reviews to suggest a major quality difference between these aftermarket brands for this part. Your choice can confidently be based on price and availability. They are all designed to be direct-fit replacements, making installation straightforward.
| Part Type | Typical Price Range |
|---|---|
| New Aftermarket | $21 - $49 |
| New OEM | $45 - $75 |
| Shop Labor | $60 - $120 |
Frequently Asked Questions
Where is the brake light switch located on a 2006-2013 Volvo C70?
The brake light switch is located in the driver's side footwell. You will find it mounted on a bracket attached to the top of the brake pedal arm, up under the dashboard.
Is replacing the brake light switch a DIY job?
Yes, this is a very DIY-friendly repair. It typically requires removing a lower dash panel with a few Torx screws, unplugging the electrical connector, and twisting or unclipping the old switch from its bracket. The entire job usually takes less than an hour. However, access can be tight, and some owners report that the retaining clips can be tricky to release without breaking the old switch.
Can a bad brake light switch really stop my car from shifting?
Yes. For safety, your C70 has a shift interlock system that requires the brake pedal to be pressed before you can move the shifter out of Park. The brake light switch is what tells the system the pedal is pressed. If the switch is broken, the signal is never sent, and the shifter remains locked.
Are there any recalls for the C70 brake light switch?
No. As of early 2026, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for the brake light switch on the 2006-2013 Volvo C70.
