How to fix my cruise control Chevrolet Venture, GM vehicles
If the cruise control doesnt work on your GM vehicle, start by checking the condition of the brake lights and high mount brake light. The PCM monitors the brake lamps. If any of the bulbs are burned out or are the wrong type, the powertrain control module (PCM) will “inhibit” the cruise control. Yeah, that means it won’t work.
If the bulbs are good, check the vehicle speed sensor signal.
