1st time on ANY forum. So here I go....I have a 99 S80 2.9. Slammed the trunk lid to hard last week and broke a breaklight bulb & now I have message on dash that a position light is out. I have all bulbs numerous of times...found all good. Even replaced some just in case. But I did notice the lights on rear view side mirrors are not working. Replaced bulbs today to no avail. Is there a modular or something/somewhere in the trunk that would go bad?:(

Position lights are the front lights, as well as the rear lights. Sometimes, you have to replace all the bulbs in the rear to get the system to recognize that they are all there. System operates on the resistance of the bulbs, and if there are older bulbs that are near death, they will give a false signal, or so my mechanic tells me.
