Recall No. 05S28. It is for the speed control deactivation switch (cruise control switch located in the engine compartment near or on the master cylinder). Just make sure this vehicle is not part of the recall population. I haven't ran across too many Navis that do, but a ton of F-150's and Expeditions that are. The switch is hot (energized) at all times with a 12v current even when the engine is turned off. The switch has the propensity to overheat and catch fire causing catastrophic damage to the vehicle and surrounding structures. Trust me on this. Just make sure that the recall repair has been performed before purchasing.
