If your vehicle’s cruise control fuse is blown, the system will stop working. Older vehicles use vacuum to control the throttle for the cruise control, and in this case a vacuum leak can heavily affect the cruise control. However, modern cruise controls are fully electric and in most cases will not be affected by a vacuum leak if the check engine light is not illuminated. The function of a check engine light or MIL (Malfunction Indicator Light) is to communicate engine or mechanical failures in your vehicle to prevent an accident on the road. Often when there are other failures or engine faults, the MIL will light and the cruise control with a flicker to signal it has been disabled for safety reasons. Once the cruise control or other issues are fixed, all the lights should go back to being turned off.
How much does it cost to fix cruise control malfunctions?
Check the system with an OBD2 scanner to look for any trouble codes related to the cruise control.

While this fault can cause issues with the cruise control system itself, there could also be an effect on the acceleration of your vehicle. That’s why you want to have it looked at as soon as you notice a problem. Let’s take a quick look at the reasons your cruise control may have stopped working. The instrument panel fuse box is on the driver side of the instrument panel.

What's the 2006 Ford f150 cruise control fuse location?
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.
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.
Sometimes, the cruise control stalk itself can be defective, leading to cancellation issues. The stalk is the lever or button on the steering column that controls the cruise control functions. If it becomes worn out or damaged, it may not properly communicate with the cruise control module, resulting in the failure to cancel. In such cases, replacing the cruise control stalk may be necessary to restore proper functionality. Remember, it’s essential to address cruise control issues promptly as they can affect your driving experience and convenience.
Can cruise control cause check engine light?
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.

Bad actuator vacuum, hose, or cable –The actuator vacuum is what connects and activates the throttle control. The fault may be with the hoses in the vacuum actuator or the cable linking the system together. Like any electronic system on a vehicle, the cruise control system is susceptible to component and wiring failures. Software updates may also be needed to change voltage levels and values that determine settings such as acceleration rate and power consumed.
Before you replace or repair any electrical parts, check the appropriate fuses or circuit breakers. The brake pedal switch is responsible for turning the brake lights on and off based on the pedal position. Cruise control systems are designed to disengage whenever your brake pedal gets pressed. There’s a switch fixed to the bases of the brake pedal and if cruise control does not deactivate when braking then it’s a sign that this switch is faulty. Bad brake pedal/light switch — This means communication between you, cruise control and the car is interrupted, and you can’t have immediate manual control of the car. This switch is located on the brake pedal assembly and allows current to flow to the cruise control module to signal cruise deactivation.
The reason for your cruise control not working could be as simple as a blown fuse to really complex electrical problems. Defective switches, sensors, and even “check engine” light, all could contribute to this problem. If something electrical in your vehicle stops working, check for a blown fuse first. Determine from the chart, or the diagram on the fuse box lid, which fuse or fuses control that device.
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?
If you drive an older vehicle with cruise control, you might have an issue with the vacuum actuator or the cable that connects to the throttle. If there has been damage done to the vacuum hoses or the actuator, the cruise control will stop working altogether. When a sensor fails, the cruise control can stop working and the speedometer might act strange as well. The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems.
This can be a safety concern, as the vehicle may not respond to braking while the cruise control is active. If you experience issues with cruise control not canceling when the brakes are applied, it is recommended to have the brake switch inspected and replaced, if necessary. They have a vacuum actuator connected to the throttle linkage that opens and closes the throttle to maintain the vehicle’s speed. If you find a burnt brake light, just replace it and test the system again. Cruise control is a sophisticated electronic system that is able to hold/accelerate and decelerate the vehicle by the push of a button.
You could start to notice issues with acceleration or have trouble with the speedometer. To play it safe, it’s always best to have the cruise control repaired as soon as you notice a problem. The cost to repair your cruise control system depends on what caused it to fail.
The under-hood fuse box is located in the engine compartment on the driver’s side. The switch circuit or fuse may just need to be replaced for the problem to resolve. If cruise control does not engage after the green light appears, the problem is most likely due to a blown fuse. This guide has outlined the most common solutions for this easy-to-fix problem. You won't need to spend all day replacing parts and it's easy to do it yourself. If the system can’t detect the vehicle’s speed or detects a problem with the speed sensor, it will stop working.
