Where is the blind spot sensor on a Ford Explorer?

The blind spot sensor on a Ford Explorer is typically located on the side mirrors of the vehicle. These sensors use radar technology to detect vehicles in the driver's blind spots, providing a visual alert to the driver when another vehicle is present.

Understanding Blind Spot Sensors in Ford Explorers

Blind spot sensors are an important safety feature in modern vehicles, including the Ford Explorer. These sensors use radar or camera technology to monitor the areas on the sides of the vehicle that the driver cannot easily see, known as the "blind spots." When another vehicle enters these blind spots, the sensors detect its presence and provide a visual alert, usually in the form of a light on the side mirror.

On the Ford Explorer, the blind spot sensors are typically located on the side mirrors, near the outer edge. This placement allows the sensors to effectively monitor the areas on both sides of the vehicle. The sensors are integrated into the mirror housings, so they are not easily visible from the outside.

Importance of Blind Spot Monitoring

Blind spot monitoring is a crucial safety feature, especially for larger vehicles like the Ford Explorer. Blind spots can be particularly problematic on SUVs and trucks, as the size and height of these vehicles can create significant areas that the driver cannot see directly. By using blind spot sensors, drivers can be alerted to the presence of other vehicles, reducing the risk of collisions during lane changes or merging maneuvers.

Maintaining Blind Spot Sensors

• Keep the side mirrors clean and free of obstructions, as dirt or debris can interfere with the sensor's ability to detect other vehicles.


• Regularly check the sensor's operation by having a friend or family member stand in your blind spot while you observe the mirror indicator light.


• If the blind spot sensor system is not functioning correctly, have it inspected and repaired by a qualified Ford technician.

By understanding the location and importance of the blind spot sensors on your Ford Explorer, you can ensure that this safety feature is working effectively to help you navigate the road with confidence.

Where is the blind spot monitor sensor located?

Blind spot monitor sensors are typically located on the rear sides of the vehicle, concealed behind the rear bumper cover. Some systems may also use cameras under the side view mirrors or utilize sensors in the rear quarter panel or even tail lights.

Common locations

• Behind the rear bumper: This is the most common location for the radar-based systems that many modern cars use. There is a sensor on each side of the rear of the vehicle. 
• In the side view mirrors: Some newer systems use cameras located on the underside of each side view mirror. 
• In the tail lights or quarter panel: In some vehicles, the sensors are integrated into the tail lights or the body panel behind the bumper.

How to identify them

• Radar sensors: These are usually hidden and not visible from the outside, though they are often located near the rear reflectors. 
• Camera systems: If your car uses cameras, they will be a small lens on the underside of the side view mirrors. 
• Check your owner's manual: For the most accurate information, consult your car's owner's manual, which will detail the exact location for your specific make and model. 

How to clean a blind spot sensor?

Use isopropyl alcohol and a clean rag and clean all around the blind spot monitor. The back of the monitor must be as clean as possible so sealant will adhere to it. Let the area dry completely before attempting to seal the monitor and wiring.

BLIS uses radar sensors on both sides near the rear of the vehicle. When a vehicle is detected in your blind spot, you are alerted with an indicator light in the side view mirror.

How to fix blind spot monitor system malfunction?

To fix a blind spot system fault, start with simple resets like restarting the car or disconnecting the battery, then clean the sensors and check for physical damage. If the issue persists, the fault could be due to loose or damaged wiring, a faulty sensor, or a software glitch, which may require a diagnostic scan tool to identify specific error codes and professional service for complex repairs. 
Simple troubleshooting steps

• Restart the vehicle: Turn your car off completely, wait about 30 seconds, and then turn it back on. Drive for a few minutes above 10 mph to see if the system reinitializes automatically. 
• Disconnect the battery: If restarting doesn't work, disconnect the negative terminal of the 12v battery for about 10 minutes to perform a full electronic reset. Reconnect it and check if the warning light has cleared. 
• Clean the sensors: Use a soft cloth and isopropyl alcohol to clean the sensors, which are often located in the rear bumper or side mirrors. Dirt, mud, or debris can block them, triggering a fault message. 
• Inspect for physical damage: Check the sensors and their surrounding areas for any cracks, loose parts, or signs of impact. Look for any aftermarket accessories like bumper stickers or bike racks that might be interfering with the sensors.

Advanced diagnostics and repairs

• Check the wiring: Inspect the wiring harnesses for loose connections, corrosion, or damage, especially around the rear sensors and taillight assemblies. 
• Use a diagnostic scanner: A diagnostic scanner (OBD2 scanner) can read specific fault codes. This can help pinpoint issues with the radar sensors or other related modules. 
• Seek professional service: If the fault continues after these steps, a technician may need to replace a faulty sensor, update software, reprogram a module, or perform other complex repairs.
