CHRYSLER issued a recall on the RAM model

On certain Ram 3500 vehicles, the headlamp switches used in this truck series operate under a high current load which results in switch internal temperatures above the 100 degree centigrade limit for the internal lubing grease. This heat will cause the grease to break down and increase the resistance in the switch resulting in eventual switch failure. Correction: Headlamp switches will be replaced and a relay will be included in the park lamp wiring circuit causing the headlamps or park lamps to go out.
