Where is the cruise control servo motor located?
The cruise control servo motor could be anywhere in the engine compartment. There are two main components of the cruise control system: the controller and the servo. The controller integrates all the inputs and tells the servo how far to actuate the throttle plates.
What to do if your cruise control fails?
If the cruise control system fails to maintain the set speed, check the throttle linkage adjustment. Use your service manual for the correct procedure for adjusting the linkage. If the linkage is properly adjusted, check for vacuum leaks at the servo. Turn the engine of if turned on, and use jumper wires to energize the servo solenoid valves.
Why does my cruise control turn off when I Touch the brake?
Brake lights? Yup, cruise controls have a switch to toggle them off when you touch the brake pedal, and many use the same switch as the brake lights. If one of the brake lights has failed, the cruise control thinks the brakes are on all the time and won’t come on. Same result if the switch is incorrectly adjusted or broken or jammed.
What are the symptoms of a bad cruise control vacuum?
Speed surges while cruise control is engaged One of first symptoms most commonly associated with a problematic cruise control vacuum reservoir is the speed surging while the cruise control is engaged.
The cruise control servo motor could be anywhere in the engine compartment. There are two main components of the cruise control system: the controller and the servo. The controller integrates all the inputs and tells the servo how far to actuate the throttle plates.
What to do if your Cruise Control Controller is defective?
Use the digital volt ohm meter to check the resistance of the servo solenoid windings. Check your service manual for the correct readings. Check for a vacuum leak at the servo. If the results of these checks are satisfactory, the controller is usually defective. Buy a new part at your local parts store or dealer.

What are the components of a cruise control system?
There are two main components of the cruise control system: the controller and the servo. The controller integrates all the inputs and tells the servo how far to actuate the throttle plates. Normally, there is no way you can service this item, so if you trace a problem to the controller, you’ll have to buy a new one.

How does a servo control servo motor work?
Servo control Servo motors are controlled by sending a PWM (pulse-width modulation) signal to the signal line of the servo. The width of the pulses determines the position of the output shaft. When you send the servo a signal with a pulse width of 1.5 milliseconds (ms), the servo will move to the neutral position (90 degrees).
How does the steering wheel work with cruise control?
In some cars, when cruise control has been set (using a button on the steering wheel, of course), sensors on the front bumper adjust the speed of the car to provide a cushion of time and or distance between your car and the one in front of you on the highway.
What should I do if my cruise control is not working?
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? 21 people found this helpful.
How does a cruise control system work on a truck?
Some older systems, used on cars or trucks that don’t have throttle-position sensors, may have a rod that moves in and out of a magnetic coil to tell the controller the throttle position. There are also two electrically operated solenoid valves. One valve admits vacuum to the diaphragm chamber to add more throttle.
Where is the cruise control button on a Ram 1500?
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.
