Symptoms of a Failing Cruise Control System

For many drivers, cruise control is a non-negotiable vehicle convenience. Not only does it give drivers a break from having to engage the throttle, but it also improves gas mileage. Among the electrical components of your vehicle, cruise control is one of the most reliable, but occasionally, it, too, can fail. If you have a long commute, Mobile Installation knows how important your cruise control can be. The next time you’re cruising down the highway, keep an eye out for these symptoms. If you notice anything unusual, take your vehicle to your local technician for an inspection.

Not Maintaining Consistent Speed

When you’ve set the cruise control, it should always maintain the speed you’ve set. If you notice that your speed fluctuates after setting it, your system may be malfunctioning. To determine if you have a problem, try resetting the system. To do this, turn the cruise control off by disengaging the switch in your car.

Next, turn the system on again, set a speed, and reapply cruise control. Sometimes resetting the system is all it takes to restore functionality, but if you continue to experience increasing or decreasing speed, you have a problem. Take your vehicle to your local mechanic to have it checked out.

The System Does Not Engage

If your cruise control won’t engage or disengage when you attempt to turn the system on or off, your vehicle has a problem. Keep in mind that the system is only made to engage at speeds above 25 mph. If you’re traveling below the minimum speed and this occurs, you have nothing to worry about. A system that doesn’t engage or disengage may be due to any of the following factors:

●        A faulty vehicle speed sensor

●        Throttle malfunction

●        Vacuum bleed switch malfunction

●        Blown fuse

●        Defective transmission signaling

●        Faulty speed control assembly

Each vehicle manufacturer has a slightly different procedure for turning on cruise control. Make sure you’ve read and followed the instructions before assuming your system is faulty. If it continues to malfunction, have your vehicle inspected by a certified technician.

Dashboard Cruise Control Light Issues

If your cruise control light remains on even after you turn the system off, you may have a problem with your speed control assembly. This issue is usually due to a malfunctioning fuse or a communication disruption in your vehicle’s computer. If the latter occurs, you’ll need to replace your vehicle’s speed control assembly. You may also find that the cruise control light does not illuminate when you attempt to activate the system. A faulty light could indicate a problem with the cruise control switch, or an issue elsewhere in the system.
