cruise control

You will need to trouble shoot for the problem checking the controls in and the controlled out put from the cruise control module. The inputs to the module are power, ground, brake light (and clutch pedal input where applicable) speed set, speed resume, cancel ect.... The module processes the inputs and works an actuator to operate the accelerator and control the vehicle speed. There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subrcription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
