How do you fix the cruise control if it is sticking in a 92 Chevy Van?

Often, the most difficult part of a repair project is the actual diagnostic phase in which youd etermine what's causing the problem. Without more information it is impossible to tell you what's wrong and what to replace. It can be the module, the brake sensor, switch, connector, speedometer, brake light ground fault or any of a number of other problems and it's impossible to tell you which it is without digging into the vehicle.
