having with other similar year RAM trucks. Typically you turn the cruise control on and then use the steering wheel buttons to set the speed or to change speed up and down. Did you try reading the owners manual? 11 people found this helpful. The button to turn the cruise on/off is on the steering wheel right next to the accel, set/decel buttons.

What to do if you have a hole in your cruise control?

A cruise control mechanism has a vacuum powered actuator connected to the control module by vacuum lines. Check for holes in the vacuum line of your cruise control by starting the engine and opening the car hood. Listen for signs of vacuum leaks.

The speed sensor is like a small plug protruding off the transmission with various wires attached to it. Visually check the wires for any signs of damage. A faulty or damaged wire on your speed sensor means that the speed sensor cannot relay your vehicle’s speed. A power surge can easily blow out the fuse of your cruise control mechanism.

How is the cruise control connected to the actuator?

The throttle and the actuator mechanism of your car’s cruise control system are connected together with metal chains called the throttle linkage. The throttle linkage can easily break away when driving on rough terrain disabling the control mechanism of the control module.

What does the cruise control switch do on a car?

The cruise control switch is what you use to set your cruising speed. This information is transmitted to the engine control unit and cruise control module in order to sustain the acceleration speed.

Where are the fuses on a Honda Civic cruise control?

Open the under-dash fuse box below the instrument panel. Check your owner’s manual to determine which fuse number corresponds to the cruise control feature. Fuse numbers vary by model and year. The fuse box cover displays and maps the location of each fuse. With the fuse puller tool or needle nose pliers, remove the fuse from the fuse box.

How do you turn off cruise control on a car?

Normally, you press the brake pedal to turn off cruise control. The brake light switch must be detected by the cruise control system for this to happen. If it cannot detect the switch, then cruise control will disable itself automatically until the brake light switch issue is fixed.

Why is my cruise control not working after the green light?

If cruise control does not engage after the green light appears, the problem is most likely due to a blown fuse. Open the under-dash fuse box below the instrument panel. Check your owner’s manual to determine which fuse number corresponds to the cruise control feature. Fuse numbers vary by model and year.

A faulty or damaged wire on your speed sensor means that the speed sensor cannot relay your vehicle’s speed. A power surge can easily blow out the fuse of your cruise control mechanism.

What to do if your Cruise Control is broken?

Using a fuse puller, pull the fuse off the panel. Examine the cruise control fuse or use a fuse tester to determine if the thin metal strip inside the fuse is broken. If so, install a fresh fuse of the same amperage. A cruise control mechanism has a vacuum-powered actuator connected to the control module by vacuum lines.

The cruise control fuse is normally found in the fuse panel located below the steering wheel. Remove the cover of the fuse panel and locate the fuse for the cruise control using the fuse diagram on the fuse panel.

How do you deactivate cruise control on a car?

Deactivating your car’s cruise control is done by simply applying slight pressure to the brakes. Below are the materials and instructions you will need to troubleshoot problems with your car’s cruise control.

Check the fuse for the cruise control. If you have an ABS Brake Light on (or any ABS problem codes set), a failed wheel speed sensor could cause cruise control to not work properly, since cruise control uses wheel speed sensor data.

Where is the fuse on the cruise control?

Figure 1. A good fuse (on the left) compared to blown fuses (on the right). This switch is located on the brake pedal assembly and allows current to flow to the cruise control module to signal cruise deactivation.

How does a cruise control module detect speed?

The only way your cruise control module is going to know how fast the vehicle is moving is if the vehicle speed sensors feed this information to it. If the module cannot detect the speed because of faulty speed sensors, then the cruise control system will automatically deactivate.

Can a brake light disengage cruise control?

Brake Light Switch – As cruise control is automatically cancelled by depressing the brake, some vehicles may disengage cruise control if it cannot detect the brake light switch. Brake Lights – In some systems, cruise control is disabled when a brake light is blown.

The cruise control not accepting settings above a fixed speed could be caused by any number of issues from a circuit problem to a faulty sensor to a problem with the main control unit.

Why is my cruise control not working on my Mercedes CLK 320?

Is the brake lights remaining permanently on the reason for the cruise control on a 2000 Mercedes CLK 320 not working? If the brake light switch is faulty and sending a message to the cruise control computer that the brakes are being applied, the cruise control will not engage.

Brake Light Switch – As cruise control is automatically cancelled by depressing the brake, some vehicles may disengage cruise control if it cannot detect the brake light switch. Brake Lights – In some systems, cruise control is disabled when a brake light is blown.

How does an adaptive cruise control system work?

Adaptive cruise control systems, sometimes called “smart” cruise, use radar or laser detection to maintain safe distances from vehicles ahead. Some adaptive cruise control systems merely reduce engine speed to maintain distance, but some of the newest adaptive cruise control systems can also engage the brakes to slow or stop the vehicle.

What to do if your Cruise Control is not working?

A diagram of the stoplamp switch. This switch can be found on the steering wheel, although some switches can be found on the dashboard.

What happens if the cruise control reservoir fails?

If the cruise control vacuum reservoir fails, the cruise control system will be left without its necessary vacuum reserve, and as a result, will not be able to hold the vehicle at the set speed or rate of acceleration. 3. Engine performance issues

Why is the vacuum important to the cruise control system?

As the cruise control vacuum reservoir holds vacuum for the cruise control system so that it may operate properly even when engine vacuum is low, it is very important to the proper operation of the cruise control system, and any issues with it can cause problems for the entire system.

What do you need to know about a cruise control switch?

The cruise control switch is the electrical switch that is used to control the various functions of the cruise control system.
