what are the most common problems with a cruise control that doesn't work? on 1999 Toyota Corolla

i have checked all the components except the speed sensor and the relay. the speedometer works so i assume the speed control sensor is ok. that leaves the relay and i'm not sure which one that is. any suggestions?
