Cruise control will not engage or kicks out
All cruise control systems have certain things in common. First, they must receive power from the ignition switch. Next, they must see a “brake off” signal from the brake switch mounted under the dash above the brake pedal. The most common failure point is either of these two parts. If the cruise engages and lets go, that’s most often a sign of a brake switch that’s intermittent, mis-adjusted, or has a short in the wires (head right for a broken wire in the connector if you own a Ford). In fact, even if you replace the switch, check the wires in the connector if you still get intermittent operation. If that checks out, test for constant power from the ignition switch to the cruise module.
