The cruise control clutch release switch is only located on manual transmission vehicles. These vehicles have a clutch pedal, is depressed.
The cruise control works on a circuit system. If the clutch pedal is not pressed in at all, the cruise control circuit is closed, allowing it to be set at a certain speed. Once the clutch is pressed in, the circuit will be open and the cruise control will be cancelled so you will set your speed by setting your foot on the gas pedal.
If the cruise control clutch release switch stops working while it is in the closed position, the engine will race as soon as you press the clutch and while the cruise control is set. You will need another way to cancel the cruise control system, such as pushing the button on your steering wheel or pressing the brake pedal. In addition, if the cruise control clutch release switch fails while it is in the open position, the cruise control will not work at all and you will not be able to set the speed.
The cruise control clutch release switch and brake switch are on the same circuit, so if one fails, so will the other. If you suspect your clutch release switch is not working properly, check your brake lights. This can be done with the help of a friend. With your car running, push on your brakes and have your friend let you know if the lights illuminate or not. If they do not, chances are the switch has gone bad. This means the brake switch and the cruise control clutch release switch need to be replaced.
Since the cruise control clutch release switch can go bad and fail over time, it is important to know the symptoms.
Signs that indicate your cruise control clutch release switch needs to be replaced are:
- The cruise control will not cancel when you press the clutch pedal down
- The cruise control will not set
- Your brake lights are not working
If you are experiencing any of the symptoms above, book a service with a mechanic.
