Cruise Control doesn’t work?

A blown fuse is the simplest to explain. If the fuse of your cruise control is bad, the cruise control won’t work. If the speed sensor or speedometer isn’t working, the cruise control won’t work either, since this feature is partially responsible for making the cruise control function properly.

What would cause cruise control not to work?

When the fuse of for the cruise control blows, the cruise control will stop working altogether. A vehicle’s cruise control may stop working if the vacuum actuator has stopped working or if there is damage to the vacuum hoses. The system may also fail if the cable linking the actuator to the throttle is broken.

How much does it cost to fix cruise control?

Cruise Control Repair Cost If you need to replace a cruise control or brake switch, you might spend between $125 and $350, including parts and labor.

How do I reset my cruise control?

The cruise control system will be reset to the speed you are travelling when you release the knob. For a quick reset, accelerate with the accelerator pedal to the desired speed, then press and release the “SET/COAST” button.

Why cruise control is bad?

Sluggish reaction times. We mentioned how cruise control makes it easy to get too comfortable and not stay alert while driving, but it can also lead to slower reaction times in the event of traffic coming to an unexpected stop, another driver cutting you off, or a pedestrian or animal crossing into your path.

Why does my cruise control only work sometimes?

Most of the time this is caused by a bad brake switch. If the switch is shorting out, then it will cause the computer to think that the brakes are being applied, which turns off the cruise control. If the switch is fine, then it may have a bad speed sensor or the cruise control switch itself is bad.

How do I know if my cruise control switch is bad?

Symptoms of a Bad Cruise Control Switch

  1. Cruise Control Stops Suddenly.
  2. The Switch Does Not Turn On or Off.
  3. A Blown Fuse.

How Cruise Control Works

Cruise control, if your automobile is equipped with it, can help you be more relaxed and aware while driving for extended periods of time. images courtesy of gabrieletamborrelli / Getty In addition to reducing stress and weariness on lengthy rides, cruise control may also be potentially harmful if not used correctly. You may have one of the nine issues listed below if your cruise control is not operating properly in your car.

Why Is My Cruise Control Not Working?

There are a few fundamental ways that cruise control might fail, depending on how the system is configured. Although you may not be able to do much with ETCS cruise control systems, there are a few things you can do to make sure they are working properly: Brake Light Switch– Because cruise control is automatically discontinued when the brake pedal is depressed, certain cars may disable cruise control if the brake light switch is not detected by the vehicle. Brake Lights– In certain systems, cruise control is deactivated when a brake light is blown.

  • Several cars employ fuses and relays to safeguard the cruise control actuator circuit, which is found on some SUVs and pickup trucks.
  • Spiral Cable– The cruise control switch is commonly found on the steering wheel of many automobiles.
  • Control Switch– If the internal contacts on the cruise control switch get worn out, the cruise control switch may be unable to communicate with the CCM.
  • Check Engine Light– On some contemporary cars, particularly those equipped with ETCS, cruise control may be deactivated if there is anengine or gearbox problem.
  • Photo credit: Hans Haase / Wikimedia Commons Vacuum Leak– Some older automobiles employed vacuum actuators to operate the throttle body during cruise control operation.
  • In the case of a vacuum leak, the engine’s idle speed may be increased, and a fuel trim code may be set.
  • The CCM may make use of a VSS feed from the ECM, instrument cluster, or transmission to perform its functions.
  • Electrical Issues– Because the majority of cruise control systems are comprised of electrical or electronic components, any diagnosis should entail a comprehensive examination of the source voltage, wire harnesses, and connection points.
  • If your cruise control is not functioning properly, you should avoid operating it until it has been fixed.

After you’ve evaluated your cruise control system on your own, take your car to a reputable technician for a checkup and a couple of diagnostics and repairs.

7 Reasons Why Cruise Control is Not Working

(This page was last updated on January 7, 2022.) Since the late 1950s, cruise control has been a part of automobiles. There was a time when this helpful function could only be found in a small number of different model automobiles. Nowadays, it appears that practically every type of automobile on the road is equipped with a cruise control option.

How Does Cruise Control Work?

If you often drive long distances, especially on the highway, cruise control allows you to lift your foot off the pedal while the car maintains the same speed, allowing your leg to take a breather as you drive. This may appear to be only a luxuries feature rather than a need, but many people rely on it to ensure they are driving safely at all times. However, while there are various variations on the theme of cruise control, the fundamental components remain the same across all implementations.

With the information provided by the speed and throttle position sensors, the engine computer can calculate how much the throttle plate needs to open or shut in order to maintain the desired speed.

When driving at a given speed, the throttle position will be different in each gear, especially when traveling over hills.

What About Adaptive Cruise Control?

In comparison to traditional cruise control systems, adaptive cruise control is a newer, more advanced cruise control system that maintains vehicle speed in response to traffic in front of you. Traffic conditions and the number of drivers on the road at any one moment frequently change, causing traffic to vary. Traditional cruise control systems are unable to function well without regular input from the driver, which defeats the point of cruise control in the first place. It employs radar or cameras to assess the speed of approaching traffic as well as the following distance between you and the vehicle in front of you.

This function is frequently employed for the purpose of automating brakes as well.

Cruise Control Problems (Accelerating or Maintaining Speed)

If the cruise control system on your vehicle fails and stops functioning entirely, you may not consider it to be a major problem right away. You’ll most likely conclude that you won’t be able to utilize cruise control until the problem is resolved. However, it is possible that the problem with your cruise control is due to an acceleration problem as well. In reality, there are components of cruise control that, if they are not functioning properly, might have a negative impact on acceleration performance.

Common Causes of Cruise Control Not Working

There are a variety of probable reasons why your cruise control isn’t working.

The following are the top six most prevalent reasons for this problem. Examine each of these places to see if they are the source of your cruise control problem or not. In many circumstances, the solution to the problem is not that difficult or expensive to implement.

1) Cruise Control Switch

The cruise control switch is used to select the speed at which you will be traveling. This information is provided to the engine control unit and the cruise control module in order to maintain the acceleration speed during the acceleration. The cruise control switch’s contacts may wear out over time. If this happens, the module and unit may not get the essential speed information it need to keep the acceleration running. As a result, the system will deactivate completely and the current cruise acceleration setting will be cancelled.

2) Brake Light Switch

Normally, you would deactivate cruise control by pressing the brake pedal. To accomplish this, the cruise control system must first recognize the presence of the brake light switch. If it is unable to identify the switch, cruise control will be turned off automatically until the problem with the brake light switch has been resolved.

3) Blown Fuse

The electrical components of the cruise control system are safeguarded by fuses to ensure that they operate safely. It is possible to blow a fuse in your car, just as it is in your home. This will result in the cruise control system being turned off until the fuse has been replaced properly.

4) Check Engine Warning Light

If your vehicle’s check engine light illuminates, it often indicates that there is a problem with the gearbox or engine. As a safety measure, if the engine control unit detects this fault, it may disable your cruise control system as a result of the detection. The cruise control will remain disabled until you have resolved the engine problem.

5) Vehicle Speed Sensor

Most automobiles are equipped with a small number of vehicle speed sensors, which communicate information about the vehicle’s speed to the engine control unit and cruise control module. Only if the vehicle speed sensors are feeding this information into your cruise control module will your cruise control module know how quickly your car is driving. If the module is unable to detect the vehicle’s speed due to defective speed sensors, the cruise control system will be deactivated automatically by the vehicle.

6) Electrical Issues

The cruise control system is comprised of a number of electrical components that are interconnected. When the cruise control stops working, it’s important to examine the connectors and wire harnesses, as well as the ground straps, among other things. In addition, make certain that the source of the voltage is still giving power to the system. If any of these components are loose or broken, this might be the cause of the cruise control not working properly.

7) Loose or Broken Cruise Control Cable

Vintage autos with cruise control feature two throttle cables: one for the gas pedal and a second to regulate the cruise control function. It is possible that these wires will extend over time. If the cruise control cable has been stretched or damaged, the cruise control system will be unable to effectively operate the throttle plate.

Cruise Control Not Working? (Here’s How To Fix It)

A car on the road nowadays that does not have cruise control would be tough to come across these days. When working well, this feature makes driving long distances much simpler, but when it fails, it may be a source of frustration. Understanding the reasons why your cruise control stopped working can help you to have the problem rectified as soon as possible, allowing you to have a more pleasurable journey. Despite the fact that this defect can cause issues with the cruise control system itself, it may also have an impact on the acceleration of your car.

First, let’s take a short look at the reasons behind this decision.

It can also be caused by problems with the throttle control system or the anti-lock braking system (ABS).

It is possible that a damaged vacuum line is responsible for the problem with earlier cruise control systems. Listed below is a more in-depth breakdown of the various reasons why your cruise control isn’t working:

Causes of Cruise Control Stopped Working

Fuse boxes are used to regulate the operation of all electrical systems in the car. Your cruise control system is connected to a fuse, which might be blown if there is a short circuit or other problem with the system. The cruise control system will not function at all if the fuse is not in excellent working order. It’s not difficult to locate and replace a blown fuse, which is a blessing. You can discover the fuse for the cruise control technology in your owner’s handbook.

2. Defective Brake Pedal Switch

The brake pedal switch is in charge of turning on and off the brake lights depending on where the pedal is pressed on the pedal. Whenever the brake pedal is depressed, cruise control systems are meant to disengage and prevent damage to the vehicle. It is possible that the cruise control will cease operating if there is a problem with the brake pedal switch because it is hooked into it. When the brake pedal switch fails, the automobile incorrectly assumes that the brakes have been applied, resulting in the system being turned off automatically.

3. Malfunctioning Speed Sensor

Sensors for speed are installed on each of the wheels and differential. The objective of these sensors is to measure the speed of the wheels in order to decide whether or not traction control is required. Aspects of the cruise control system that include the speed sensors are also included. When a sensor fails, the cruise control may become inoperable, and the speedometer may begin to behave strangely as a result. If there is a problem with a speed sensor, it is common for an ABS warning light or a check engine light to illuminate on the dash when the problem occurs.

4. Electrical Issues

The cruise control system is electrical, and it is comprised of a number of components that all work together to enable the system to function. If the cruise control does not function properly, you should look for a problem with the wiring harness and accompanying connectors. In addition, you must check that the voltage source is capable of delivering sufficient power to the system. Even the tiniest flaw might result in malfunctions with the cruise control system. A problem with the cruise control lever or buttons can occur in numerous instances, resulting in the cruise control not engaging.

Examine the system using an OBD2 scanner to see if there are any issue codes relating to the cruise control system.

5. Damaged Vacuum Actuator, Hoses or Cable (Older cruise control)

A problem with the vacuum actuator or the cable that connects to the throttle may occur if you drive an older car equipped with cruise control.

It is possible that the vacuum hoses or the actuator have been damaged and that the cruise control will no longer function at all. Furthermore, the cable that connects the actuator to the throttle must be in good working order. If it is damaged, the cruise control will not function properly.

What is Cruise Control?

It was in the 1950s when the first vehicles were equipped with cruise control. However, it would be several years before it became a standard feature in modern automobiles. A function that is employed when going at a constant pace is cruise control. This electronic device enables you to select a specified speed and depress the gas pedal without having to use your hands. When driving for an extended period of time, there is less weariness since you are not required to maintain your speed. The use of cruise control can also improve fuel economy, as the vehicle consumes less fuel when moving at a steady speed.

Adaptive cruise control not only allows you to travel at a specified pace, but it also assists you in maintaining a safe distance from the cars in front of you, thanks to the use of sensors in the vehicle.

Cruise Control Repair Cost

In the 1950s, the first vehicles were equipped with cruise control as standard equipment. It took several years, however, before it became a standard feature in modern automobiles. A function that is employed when cruising at a steady speed is cruise control. It is possible to set a specified speed and remove your foot from the gas pedal using this electronic technology. The weariness associated with long drives is reduced since you are not required to strive to maintain your speed during the journey.

A smart technology such as adaptive cruise control, which may be found in some contemporary automobiles, may be available.

You must take over when the vehicle in front of you slows down while using traditional cruise control, but this is not necessary with adaptive cruise control.

Why Your Cruise Control Has Stopped Working

In the 1950s, the first vehicles were equipped with cruise control. However, it took several years before it became a standard feature in today’s automobile. Cruise control is a function that is employed when going at a constant speed. This electronic device enables you to select a specific speed and depress the gas pedal without having to lift your foot from the accelerator. There is less weariness when driving over a long distance since you are not attempting to maintain your speed. The use of cruise control can also improve fuel economy, as the car consumes less gasoline when moving at a steady pace.

By using sensors, adaptive cruise control not only allows you to go at a specified pace, but it also aids you in maintaining a safe distance from the vehicles in front of you.

In the case of traditional cruise control, you must take over when the vehicle in front of you begins to slow down; however, with adaptive cruise control, this is not necessary.

Cruise Control Broken? Fix & Learn Why at Carter Subaru Shoreline, Seattle

The use of cruise control is easy to ignore, yet it may be quite beneficial on lengthy highway rides. It enables you to maintain a regular speed without having to continually modify your speed or direction. As a result, if your cruise control stops operating, your trip may become more exhausting as a result of the inconvenience. Furthermore, it might be an indication of a more significant problem within your vehicle. The following are four typical causes for the cruise control to cease working; regardless of the cause, we recommend getting it checked out at a Subaru approved repair shop as soon as possible.

4. Damaged Cruise Control Cable or Vacuum Actuator

The cruise control system in many automobiles, in contrast to today’s cutting-edge drive-by-wire and adaptive cruise control technologies, is mostly mechanical in nature. Similar to the cable that links the gas pedal to the throttle, it makes use of a cable to operate. Instead than requiring you to press a pedal, the cruise control operates on the principle of vacuum actuators. The engine speed is controlled by a tiny valve, which is controlled by a vacuum actuator, which tightens or loosens the cable as needed.

3. A Blown Fuse

A fuse is used to safeguard the electrical components that are used to operate the cruise control in automobiles that employ them. If this fuse breaks, it is typically a simple matter to replace it. It might be that the fuse itself was the only problem; but, if the next fuse breaks, it could signal deeper electrical difficulties.

2. Bad Brake Pedal Switch

As soon as you step on the brake pedal, the brake pedal switch activates, which is responsible for turning on the brake lights on your vehicle. Although this may appear to be unconnected to cruise control, everything is more interconnected than it appears. What is the best way to turn off cruise control? By depressing the brake pedal. As a result, the cruise control is typically attached to the same brake pedal switch as the brake pedal. If the switch fails, the cruise control may not function properly since your car may believe that the brakes are used.

1. Bad Speed Sensor

The speed sensor in a car does exactly what it says on the tin: it measures the speed at which your vehicle is moving forward. It also contributes to the proper operation of the speedometer. If it fails, it has the potential to cause the cruise control to malfunction. Once again, this is a symptom of a more serious problem, and it has the potential to trigger more issues in your engine. Fortunately, it’s a reasonably simple and quick fix to do.

Why isn’t my cruise control working when I drive?

The speed sensor in a car does exactly what it says on the tin: it measures the speed at which your vehicle is moving. It also contributes to the operation of the speedometer. This can cause the cruise control to become inoperative if it does not function correctly.

It’s important to note that this is yet another symptom of a larger problem that might result in even more complications for you and your vehicle. Because of this, the repair should just take a few minutes and is simple.

5 Reasons why your cruise control stops working

In some cases, if your cruise control is not functioning properly, it may not be the fault of the technology. As you are probably aware, if you use the brakes, your cruise control will be disabled. As a result, if there is a problem with your brake light switch or your brake lights, your cruise control may believe you are applying the brakes and turn itself off to protect itself. Additionally, the cruise control is controlled via a control switch. As a result, when anything becomes worn out or damaged, it ceases to function.

6 Reasons Cruise Control Isn’t Working

If all of your driving consists of short excursions punctuated by a high number of stop lights and stop signs, you may never need to use a cruise control device. However, if you are driving on a highway, it might be a handy tool. It’s especially effective for lengthy highway drives since it can help you feel less fatigued when you’re behind the wheel.

If your Subaru’s cruise control is not functioning properly, it can make driving less convenient while also signaling the presence of additional problems with the car. You’ll discover six probable causes of defective cruise control in the section below.

6. Dirty or Malfunctioning Cameras (Adaptive Cruise Control)

If all of your driving consists of short excursions punctuated by a high number of stop lights and stop signs, you may never need to use a cruise control system. It can, however, be a handy tool when traveling on roads. Because it can help you feel less fatigued while driving, it’s especially good for lengthy highway trips. In addition to making your trip less convenient, a malfunctioning cruise control system may indicate the presence of additional problems with your Subaru car. Six probable causes of a malfunctioning cruise control are listed further down on this page.

5. Blown Fuse

Because they protect the wiring and electrical components in your vehicle’s electrical system, fuses are extremely vital components of the system. If the system suddenly receives a rush of energy that has the potential to damage something, the fuse will blow, causing the circuit to be broken and preventing more damage. In order to determine whether or not a blown fuse is to blame for the problem, locate the fuse box and look for the fuse that corresponds to the cruise control. Remove it and do a visual examination of it.

A filament that is in good condition indicates that it is most likely fine.

However, we still urge that you have the situation looked thoroughly because a blown fuse might be indicative of a more serious wiring or electrical problem.

4. Malfunctioning Brake Pedal Switch

When your cruise control is functioning properly, stepping on the brake is an instantaneous method to disable it. For those of you who drive a car with a manual transmission, the same is true when you press down on the clutch pedal. A defective brake pedal switch or clutch sensor may send a signal to your Subaru, informing it that you are always pressing the brake or clutch pedal-even when you are not. As a result, it will be difficult to use the cruise control while in this situation. The fact is, it isn’t the only issue you should be concerned about.

3. Damaged Physical Components

It is possible that your car has one of many different forms of cruise control, depending on how old it is. The earliest kind of cruise control were entirely mechanical, consisting of a cable that was attached to the throttle on one end and a vacuum actuator on the other end. These mechanical systems were followed by electro-mechanical cruise control, in which a servo was in charge of regulating the throttle position. Newer systems, on the other hand, make use of the aTACmotor. There’s one thing that is constant no matter what kind of Subaru you have: there are physical components that can become damaged over time.

2. Computer Issues

Modern automobiles rely on computers to ensure that they operate at their best performance. These computers are referred to as control modules in some circles. However, many cruise control systems have their own control modules, which can be utilized in conjunction with the Engine Control Module in some cases. It is possible that the cruise control will be disrupted if one of these computers malfunctions.

Replace the control module if necessary, but verify with your dealership first to ensure that there are no technical service bulletins for your vehicle’s control module out at the time of the replacement.

Your Vehicle’s Cruise Control Isn’t Working? Here Are the Most Common Causes

If you travel long distances on a regular basis, the revolutionary cruise control system is really useful; nevertheless, it may malfunction from time to time. This article investigates the possible origins of this bothersome problem, as well as what you may do to resolve it. The version of the system we use today was devised in 1948 by blind mechanical engineer Ralph Teetor, who was unhappy with his driver’s inability to maintain a consistent pace and brake on motorways. The system was designed to minimize stress and tiredness when driving long distances.

  1. The cruise control buttons, which are often situated on the steering wheel, can be used to raise or reduce the vehicle’s speed.
  2. This system’s brain is the cruise control module (CCM), which keeps track of the speed at which the car is being driven and controls the throttle body to keep it there.
  3. The very earliest systems made use of a vacuum motor and cable, which were ultimately replaced by electric motors in more modern systems.
  4. The function is included into the engine control module (ECM), which is responsible for controlling the throttle body.
  5. The check engine light is illuminated.
  6. If the check engine light illuminates after starting the car, take it to a professional as soon as you can.
  7. In many cars, a fault with the brake lights will result in the system being permanently disabled.

If none of the brake lights are on, it is possible that the brake light switch is malfunctioning.

Even while it is not expensive to replace, doing it yourself may be challenging, therefore we recommend that you take your car to a skilled repair.

As part of the system’s protection, fuses and relays are utilized in some automobiles, and a blown fuse or relay might cause the cruise control to cease working.

Consult your vehicle’s owner handbook for specifics on where to find the cruise control fuse and relay position.

Every contemporary car is equipped with a number of speed sensors, and the CCM makes use of data from at least one of these sensors in order to maintain the specified speed.

Leak in the Vacuum As previously stated, vacuum actuators are used to operate the throttle body when the cruise control is on in earlier automobiles, as is the case with this one.

Keep an eye on the tachometer if you see any vacuum leaks because this might cause the engine to idle at higher RPMs.

If the problem persists even after all of the above components have been tested and determined to be in correct working order, the electrical system of the vehicle is the most likely source.

The cruise control button itself or one of the several cables might be the source of the problem, but a certified automotive electrician must undertake a full set of examinations in order to adequately identify the source.

3 Things To Know When Cruise Control Doesn’t Work

Intense leg, foot and ankle weariness can significantly diminish the pleasure of lengthy road trips and highway rides – but that is precisely what cruise control is for.

Allow us to repair your cruise control if it is not functioning properly at Capitol Subaru in Salem! Depending on the type of cruise control system that your automobile is equipped with, it is possible that electrical or mechanical components have failed to function.

3. Mechanical Cruise Control: Severed Cruise Control Cable

Many older automobiles are equipped with mechanical, vacuum-actuated cruise control systems that regulate the vehicle’s speed by adjusting the vehicle’s physical connection. In this case, a physical cable attached to a vacuum actuator pulls on the throttle body, opening and shutting it as necessary to achieve the desired speed. The cruise control, on the other hand, will not function if this wire is destroyed or unplugged. It’s also possible that there’s a vacuum leak in the cruise control actuator, which prevents the system from manipulating the throttle and changing your speed.

2. Modern Cruise Control: Electronic Fault

You’ll discover that the majority of the time, cruise control is controlled electronically in most modern automobiles. The Engine Control Unit of the car collects speed data from the speed sensors and manipulates the throttle to assist you in maintaining your chosen speed. That implies that technical faults, such as blown fuses, defective speed sensors, or a damaged ECU, might cause your cruise control to stop working properly. Because electrical problems in contemporary automobiles may be difficult to diagnose, you may want to have a Capitol Subaru specialist take a closer look at your vehicle if your cruise control has stopped working.

1. Adaptive Cruise Control: Bad Sensors

5. Blown Fuse

This is one that you may be able to investigate on your own. As soon as you’ve discovered and removed the fuse that’s related with the cruise control, you should thoroughly check it. If the wire within the fuse is damaged, replacing it with a new fuse may be sufficient to repair the problem. Keep in mind, however, that fuses are intended to protect electrical equipment from harm caused by an overcurrent. Even if this may have been a one-time issue, it is still a good idea to get your automobile examined to ensure that the electrical system is in excellent working order.

4. Damaged Servo, Throttle Actuator, or Cable

Over the years, cruise control has gone through a number of different incarnations. Early mechanical variations depended on a cable attached to a vacuum actuator on one end and the throttle on the other end to function. In electro-mechanical systems, the throttle was controlled by a servo, however this has been replaced by a TAC motor in contemporary electronic cruise control systems, which stands for Throttle Actuator Control. Damage to or failure of any of these components, regardless of the type of vehicle you have, might cause the cruise control to cease functioning.

3. Control Module Problems

The control module in your car is similar to a computer. Some cruise control systems feature a dedicated cruise control control module, but others rely on the engine control module to manage the cruise control. Whatever the situation may be, a failure with this computer might result in the cruise control ceasing to operate. The module that controls the cruise control in your vehicle may need to be replaced if there aren’t any recall notifications or technical service bulletins available for it.

2. Bad Speed Sensor

The speed sensor does exactly what it says on the tin: it measures the speed at which your car is going forward. Because of the damage to the speed sensor, your cruise control may not be able to determine how fast the car is driving. In certain types of situations, the cruise control may simply fail to switch on by itself. In addition, it is conceivable that a faulty speed sensor will cause the speedometer to cease operating completely.

1. Broken Brake Pedal Switch or Clutch Sensor

Surprisingly, a faulty brake pedal switch or clutch sensor may also result in the cruise control failing to function. When everything is functioning properly, pressing the brake pedal—as well as the clutch pedal if you have a car with a manual transmission—will turn off the cruise control.

If one of these components is damaged, your vehicle may believe that you are always braking. The cruise control would not be activated as a result of this action.

Cruise Control Not Working? 4 Possible Reasons in Beaverton

If you spend any length of time on the highway, you’ll understand how valuable cruise control may be. If your vehicle’s cruise control is not functioning properly, it might result in driver weariness. However, this is not the only issue that can arise as a result of a malfunctioning cruise control system. At Carr Subaru, we strive to provide you with crucial information about your Subaru, which is why we’ve compiled a list of four reasons why your cruise control may not be functioning properly.

4. Mechanical Components Have Been Damaged

If you’re driving an older Subaru, it’s possible that the vehicle has a mechanical cruise control system. Typically, a cable is linked to the throttle on one end and to a device known as the vacuum actuator on the other end of the system. This is a common configuration. The vacuum actuator will tighten or loosen the cable in response to the speed at which you have set the cruise control. A vacuum leak or damage to these components, for example, might prevent the cruise control from performing its function.

3. A Fuse Has Blown

Unless you have an older Subaru, the cruise control is almost certainly operated by an electrical device. If this is the case, it is possible that electrical problems will lead it to fail. The majority of the time, these issues will result in a blown fuse. Replace the fuse for the cruise control and see if it helps. If you’re lucky, it will be all that is required of you. Unless it works, or if the fuse breaks again shortly after, it’s probable that you have further electrical problems on your hands.

2. The Speed Sensor Isn’t Working Properly

The speed sensor does exactly what it says on the tin: it detects changes in speed. In other words, it measures the speed at which your vehicle is traveling. A malfunctioning speed sensor may be delivering incorrect information to your cruise control system if the sensor is not operating properly. A broken speed sensor, on the other hand, might cause your speedometer to be incorrect, thus it’s an issue that should be repaired as soon as possible.

Cruise Control Not Working? 4 Possible Reasons in Salem, OR

Using cruise control when driving on the interstate may be really beneficial. Because it keeps a consistent tempo for you, you may put your leg down and relax. A malfunctioning cruise control system in your Chevrolet might cause you to get more fatigued while driving, and it may also indicate that there is an underlying problem with your Chevrolet’s electrical system. The following are four probable reasons why your cruise control may not be working anymore. We recommend that you have your Chevrolet checked out by a factory-authorized technician, regardless of the reason for the problem.

4. The Mechanical Components Have Been Damaged

Your cruise control may be mechanical if you’re driving an earlier model vehicle. Typical cruise control systems are composed of a cable connecting the throttle to a component known as the vacuum actuator, which adjusts the cable in accordance with the cruise control setting.

Damage to either of these components can cause the cruise control to cease operating. A vacuum leak is a regular problem with these systems.

3. A Fuse Has Blown

Cruise control systems that are regulated electronically contain a fuse that can blow if there is an electrical problem with the vehicle. A new fuse can usually fix this issue; but, if the fuse blows again, there is most certainly a more complicated wiring issue at hand.

2. The Speed Sensor Is Damaged

The speed sensor does exactly what it says on the tin: it measures speed. It is in charge of determining the speed at which your car is going. If it’s damaged, the cruise control system may not function correctly since it may be receiving an erroneous reading from the speedometer. In addition to affecting the cruise control, a broken speed sensor can also have an impact on your speedometer and should be repaired as soon as possible.
