when on the jersey autobahn i love my cruise....allows me to drink my coffee, read a paper, juggle,...y'know, stuff like that....
the basics would be to make sure that you are operating the system correctly, as stated. if that is the case, then i would make sure the rest of the system is oeprational. could be a faulty brake switch or clutch switch (if manual) since these will cancel the cruise request.
check for power to the servo under the hood. use a test light. i forget which wire is the 'on' signal, but if you check the stickies and look for the wiring harness section (wedophones.com) you should be able to find it.
welcome to the fest. and i second the pic post request. (we like teh pictars...
