You probably do not need a new Computer Control. Carefully inspect the bulb sockets and the tail lamp assembly where the sockets are installed. The electrical contacts on both may overheat and melt or distort enough to where there is poor or no electrical contact. Lighting circuits are protected by fuses and circuit protection in the Body Control Module (BCM). Lighting circuits require an overload protected power source, ON/OFF device, lamps and good body ground to operate properly. Plastic lamps require a wire in the harness to supply body ground to the lamp socket. Lamp sockets that are exposed to moisture should be coated with Mopar® Multi-purpose Grease or equivalent to avoid corrosion. If a socket has become corroded, clean socket and bulb base with abrasive fiber sanding pad or metallic bristle brush. Replace sockets and bulbs that are deformed from corrosion that could prevent continuous body ground. Wire connectors can make intermittent contact or become corroded. Before coupling wire connectors, inspect the terminals inside the connector. Male terminals should not be bent or disengaged from the insulator. Female terminals should not be sprung open or disengaged from the insulator. Bent and sprung terminals can be repaired using needle nose pliers and pick tool. Corroded terminals appear chalky or green. Corroded terminals should be replaced to avoid recurrence of the problem symptoms. Wire connector terminals should be coated with Mopar® Multi- purpose Grease or equivalent to avoid corrosion.
