Remember, these are just a few potential causes for your cruise control system’s inability to resume speed. If the issue persists after troubleshooting, it is recommended to consult a professional mechanic who can provide further assistance and ensure a thorough diagnosis. You can replace the fuse with a new one of the correct amperage, according to your vehicle’s owner manual. If the new fuse doesn’t blow again, everything will be ok; if the fuse blows again, you have to keep searching for what is making that fuse blow. If you like to travel and own a car fitted with cruise control, you know how comfortable it can be to maintain a constant speed! When a cruise control system gets damaged, it is just as annoying as it is dangerous.
Step 3 – Check the cruise control on/off switch
When the speed sensor malfunctions, it can lead to issues with the cruise control function. If you suspect a faulty speed sensor, it is advisable to have it inspected and replaced if necessary. A speed sensor is responsible for measuring the rotational speed of the wheels or driveshaft. This information is then relayed to the vehicle’s computer system, which in turn adjusts the throttle and engine performance to maintain the desired speed. However, if the speed sensor malfunctions, it can lead to inaccurate speed readings and cause the cruise control to fail in resuming the set speed.

If you need to replace a cruise control or brake switch, you might spend between $125 and $350, including parts and labor. However, the cost to change a fuse is only a few dollars and you can perform the replacement yourself in just a matter of seconds. It would be difficult to find a vehicle on the road today without cruise control.
Step 3 – Check the clutch switch
A faulty brake switch can also be responsible for cruise control not canceling. The brake switch is designed to send a signal to the cruise control system when the brake pedal is pressed. If the switch fails to function properly, the cruise control may not receive the necessary input to cancel. To test the brake switch, you can use a multimeter to check for continuity when the pedal is pressed. If there is no continuity, it’s likely that the brake switch needs to be replaced. They can help diagnose and resolve any underlying problems with your cruise control system, ensuring a smoother and more reliable driving experience.
Even though it doesn’t explain how to fix your cruise control, it gives you an idea of where to start looking if you are going to do it yourself. Cruise control is connected to several components of the car, and when it fails it can mean that something could be wrong with the CC itself. It could also be a signal that something wrong is happening with any other component of the car. To reinstall the cover, align and engage the two hooked clips at the bottom of the cover onto the instrument panel, then lift the panel and press the top clips firmly into place. To remove the fuse panel cover, pull the panel downward by the finger slots on top of the panel.
This is a safety control as the vehicle is programmed to not go on ‘autopilot’ should the engine or mechanical issue relate to the cruise control systems. If the error or fault is with the cruise control systems, then the MIL may be lit for that as well. Another potential cause for your cruise control not resuming speed could be throttle control issues. The throttle control system regulates the amount of air entering the engine, which directly affects the vehicle’s speed and acceleration.
Check those fuses first, but check all the fuses before deciding that a blown fuse is the cause. If something electrical in your car stops working, the first thing you should check for is a blown fuse. Determine from the chart, or the diagram on the fuse box lid, which fuse or fuses control that component. Check those fuses first, but check all the fuses before deciding that a blown fuse is not the cause. When the check engine light or MIL (Malfunction Indicator Light) is on, the cruise control light may blink to signal that cruise control has been disabled.

If only one setting on your cruise control does not work, chances are high that the switch is the problem. Depending on which buttons are faulty, your whole cruise control can stop working or just some functions won’t work. I think mine might need to be replaced, but I would prefer to do it myself so that I can save some money.

In newer cars, you might be able to find adaptive cruise control, which is a smart technology. Adaptive cruise control allows you to travel at a predetermined speed, but it also helps to maintain a safe distance from the vehicles in front of you with the help of sensors. With conventional cruise control, you need to take over when the car in front of you slows down, but that’s not the case with adaptive cruise control.
In summary, common causes of cruise control malfunction include faulty speed sensors, electrical wiring issues, brake switch failure, and vacuum leaks. The most common reason a cruise control stops working is due to a blown fuse or a defective brake pedal switch. It can also be caused by issues with the throttle control system or the ABS. In older cruise control systems, it can be caused by a broken vacuum line. The speed sensor is a critical component of the cruise control system as it helps monitor the vehicle’s speed.
The speed sensor plays a crucial role in ensuring that your cruise control system accurately maintains the desired speed. Do you ever find yourself cruising down the highway, only to notice that your cruise control isn’t maintaining a steady speed? It can be frustrating and even dangerous if your vehicle starts to fluctuate in speed unexpectedly.
By understanding these potential causes, you can take the necessary steps to troubleshoot and resolve the problem, ensuring a smooth and enjoyable driving experience. Another common cause of cruise control not engaging is a faulty cruise control switch. The switch is the interface between you and the cruise control system, allowing you to activate and control it. If the switch is defective, it may not send the proper signals to the cruise control module, resulting in the system not engaging. By following these troubleshooting steps, you can effectively diagnose and address common cruise control issues.
Sometimes, the reason behind your cruise control’s failure to resume speed lies within broader engine performance problems. Various factors can contribute to engine performance issues, ultimately affecting the cruise control system’s ability to function optimally. Have you ever wondered why your cruise control fails to resume the set speed?
A defective pedal switch can also make your cruise control stop working. Remember that all cruise control systems are automatically disengaged as soon as the brake pedal is pressed down. Fuses and circuit breakers protect your vehicle’s electrical system from overloading. If electrical parts in your vehicle are not working, the system may have been overloaded and blown a fuse or tripped a circuit breaker.
Let’s take a closer look at some common issues that could cause your cruise control to struggle with maintaining speed, as well as potential solutions. If the cruise control engages when using the steering wheel buttons but not the main control button, it is likely that the main control button is malfunctioning. The speedometer speed sensor is not always the sensor used by cruise control. Some systems rely on the ABS speed sensors, others do an average and some have a dedicated speed sensor. If there is an issue with a speed sensor, it will often show with an ABS warning light or a check engine light on the dashboard. Your cruise control system is attached to a fuse that can blow if there is a short circuit or fault.
In many cases, there can be an issue with the cruise control lever or buttons causing the cruise control to not engage. The interior fuse box (1) is located under the dashboard on the driver’s side. To remove the fuse box lid, pull it toward you and take the lid out of its hinges.
