Does anyone know which signal activity module controls the rear lights, brake lights and backup lights? There are 2 modules in the front and one in the trunk. When water got in my car it ruined one of those and the stupid dealer as always cannot pinpoint which one. Also, if I buy one would I need to code it for my car to recognize or I can just remove the old on and plug the new one. Any help will be appreciated. Water rushed in on my passenger side and now I have rear lighting issues. Thats about the only thing left to figure out. My brake lights stay on regadless.
