How do you diagnose a bad cruise control switch?
Cruise control light doesn't illuminate

How do I know if my cruise control module is bad?

Is there a fuse for cruise control?
If your cruise control system is electronically controlled, it will have an associated fuse. If there's an electrical problem, the fuse will fail in order to keep other wiring from getting damaged. Try replacing the fuse. If it solves the problem and the cruise control keeps working, that's great!
Can a bad fuse cause the cruise control not to work?
A blown fuse is the simplest to explain. If the fuse of your cruise control is bad, the cruise control won't work. If the speed sensor or speedometer isn't working, the cruise control won't work either, since this feature is partially responsible for making the cruise control function properly.
How do you test a cruise control module?
A quick way to diagnose this is to try holding the brake pedal up with the top of your left foot at the same time as you are engaging the cruise control while on a test drive. If the cruise control tries to set, then the brake switch will most likely need to be adjusted. Adjustment of the brake switch is very common.
What sensor controls cruise control?
A radar sensor is usually at the core of the adaptive cruise control (ACC). Installed at the front of the vehicle, the system permanently monitors the road ahead. As long as the road ahead is clear, ACC maintains the speed set by the driver.
Does the throttle position sensor affect cruise control?
The cruise control system controls the speed of the car by adjusting the throttle position, so it needs sensors to tell it the speed and throttle position. It also needs to monitor the controls so it can tell what the desired speed is and when to disengage.
Where is the cruise control switch located?

What is a cruise control module?
When you “Set” cruising speed, the cruise control module (CCM) records the current speed, then takes control of the throttle body to maintain vehicle speed.
What does a cruise control release switch do?
The cruise control brake release switch is a switch that turns off your cruise control when your brake pedal is pressed. When you decelerate your vehicle while cruise control is turned on the cruise control module detects a loss of continuity and cancels the cruise control set speed.
Can cruise control get stuck on?
Drivers whose cruise control becomes stuck should keep calm and manoeuvre into the lane with the least traffic, then shift down gears and brake, experts say. ... “When a cruise-control system gets stuck, the braking system of the car should still be capable of slowing and halting the car, even against a revving engine.
