Actually FIXING the cruise control is usually not very hard. The hard part is finding out what is WRONG with the cruise control. Cruise control problems are usually caused by a broken clockspring (or contact assembly) in the steering column or a faulty cruise control servo assembly. Of course, there are several other possible reasons for the cruise to malfunction, but these are the most common.
The first step would be to scan your Engine Control Module (ECM) for fault codes. Please note that cruise control faults will not normally cause the Check Engine light to illuminate, so it is NOT safe to assume there are no codes present just because the light is not on. If the Check Engine light IS on, then you need to scan your ECM anyway! If there is a problem with the servo assembly, there will most likely be a code set. Problems with the clockspring will not usually set a code. A good clue that this could possibly be the problem is an inoperative horn and/or the Airbag warning light being on. (A broken clockspring will also cause these things)
