In such cases, replacing the cruise control stalk may be necessary to restore proper functionality. 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. One possible reason for the cruise control not engaging is a defective cruise control module. This module is responsible for controlling the cruise control system and ensuring that it functions properly. If the module becomes faulty or malfunctions, it may prevent the cruise control from engaging. In this case, you may need to have the module repaired or replaced by a professional technician.
Reason #1. Bad or blown fuse
If only one setting on your cruise control does not work, chances are high that the switch is the problem. Control Switch – If the internal contacts wear out, the cruise control switch may not be able to contact the CCM. This might disable cruise control completely, or it might not react to the cancel or accelerate functions. Bad actuator vacuum, hose, or cable –The actuator vacuum is what connects and activates the throttle control.
Wiring Issues
The cruise control system in your car is connected to the brake pedal switch. It’s the switch that communicates with your tail lights and turns them on as you press the brake pedal. If the switch goes bad, the signal gets interrupted, and it can reflect on your cruise control system as well. One of the easiest fixes for a bad cruise control system is to just replace a blown fuse. If this happens, you can just take a look at the fuse box by referring to the owner’s manual of your vehicle for the exact location.
How do I know if my cruise control fuse is blown?
There are a few different reasons why cruise control might not be working in your car anymore, including a broken switch, a blown fuse or relay, or faulty speed sensors. Remember, a malfunctioning speed sensor can not only affect the proper functioning of your cruise control but also impact other aspects of your vehicle’s performance. Therefore, it is essential to address this issue promptly to ensure a smooth driving experience. The brake switch plays a vital role in cruise control functionality, as it is designed to deactivate the cruise control system when the brakes are applied. If the brake switch fails, it can prevent the cruise control from canceling or disengaging properly. This can be a safety concern, as the vehicle may not respond to braking while the cruise control is active.
Can a Bad Battery Cause Cruise Control to Malfunction?
Some systems will fail on some occasions, while you’ll sometimes be able to use them regularly. It’s still better to inspect the system based on the common reasons behind its failure listed in this guide and make proper repairs. The vast majority of the time, you need to replace the cruise control cable if it’s broken.
The fault may be with the hoses in the vacuum actuator or the cable linking the system together. 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.
Electrical Wiring Issues
These types of problems can be pretty serious, so it’s definitely something you’ll want to get checked out by an experienced mechanic or technician. In this case, you might need to use a multimeter to test the fuse or relay to see if it’s still good. Typically, a relay will audibly “click” when it’s activated, so if you don’t hear the clicking noise, the cruise control relay might be bad. In most cars, a light will illuminate somewhere on your dash (or on the button itself) once you press the switch to turn on cruise control. When cruise controls experience occasional yet repeating failures, meticulously logging every instance of malfunction helps uncover patterns guiding toward root causes. When cruise control systems fail, it presents challenges adjusting to speed management without the consistent pacing it provides.

Issue Due to Malfunctioned Components:
When you're driving on the highway, cruise control can make the experience more pleasant. By allowing your leg to rest, you can avoid some of the fatigue that comes from long drives. So, if your car's cruise control doesn't work, it can be a major irritation. Below, we've listed four common reasons why cruise control may not work.
So pay attention to this reason when looking for the root cause of a malfunctioned cruise control in the jeep wrangler. Indeed, cruise control operates on electric power drawn from the Jeep’s battery. If the battery does not have sufficient power, the cruise control system cannot activate. In such situations, the Jeep’s electrical system will prioritize more critical functions, diverting electricity from non-essential features like cruise control. For the proper functioning of the cruise control system, sensors are essential as they provide crucial data to the mainframe. Unfortunately, accidents or the passage of time can lead to sensor malfunctions in the Jeep without any prior warning.
Cruise control is a sophisticated electronic system that is able to hold/accelerate and decelerate the vehicle by the push of a button. The system uses sensors and modules to communicate vehicle speed and driver inputs at a very fast rate. A failure in one of these systems can lead to total loss of cruise control operation. Remember, addressing throttle control issues not only helps restore the functionality of your cruise control but also ensures overall engine performance and fuel efficiency. Some of these new systems have laser sensors while others have cameras to calculate the right distance to follow considering the vehicle’s speed and acceleration. Any problem with the sensors will prevent adaptive cruise control from working.
Have you ever wondered why your cruise control fails to resume the set speed? The speed sensor plays a crucial role in ensuring that your cruise control system accurately maintains the desired speed. If your cruise control isn’t working properly, avoid using it until it is repaired.
It’s not safe and the best thing you can do is inspect the system based on the reasons behind a malfunctioning cruise control. Most cruise control systems are designed to disengage as you press the brake. So, if the computer believes the brakes are pressed due to a faulty switch, it will turn off the cruise control system. In case the throttle body valve gets stuck, or the throttle body gets clogged, you’ll have a hard time using your cruise control system. The worst thing that could happen in this case is if the gas pedal gets stuck in position, which also affects your driving regardless of the cruise control. With modern improvements, there’s also the introduction of adaptive cruise control which uses several drive assist systems to maintain your speed.
So, you can follow this guide to get all the information about the most common reasons for failing cruise control and get advice on how to fix it. Furthermore, sometimes the cruise control system won’t even engage if there are overarching issues with the engine or transmission that would prevent it from working. One of the first things to check if your cruise control isn’t working is the switch.
Software updates may also be needed to change voltage levels and values that determine settings such as acceleration rate and power consumed. Brake Lights – In some systems, cruise control is disabled when a brake light is blown. Aftermarket lighting, such as LED brake light conversion, might trick the CCM into thinking a brake light is blown, as LED bulbs draw less current than incandescent bulbs.
