Jay, how much fun do you want to have?? The CC amp is behind the kick panel on the drivers side of the car. You have to remove the lower dash fascia, parking brake release and, if I am not mistaken the front of the headlight switch. (not sure).. The actuator is under the intake. Remove the lower splash shield (under the engine), disconnect the linkage from the the throttle, follow the connector wiring and disconnect that, remove the retainer screws from the mounting bushings and take it out. Removal of either of or both will not affect your car. If you like to explore, check each component. Most of the time, it's one or the other. Rarely, the switch fails..
