I just purchased a 1997 C230 and the cruise control doesn't work. I was wondering what part would be the culprit? I know the cruise control switch on the column, the brake pedal switch, and the intake under the hood has a part involved in the cruise control. Is there another component? Where is the brake pedal switch located at? I was familiar w/ the cruise amplifier and actuator on my ole 84 500sel w126. I fear this will be way different in set up. Any help would be greatly appreciated. Thanks.
