I have mercedes 87 300 SDL My driver courtesy Light broke And I think it cause a short when It broke because I saw the spark!! NOW I replace the Fuse but not the light , I leave the two cables with out the light. I do not have the Sound when you open the Door And the Other light on the Other doors does not turn On. Could it be possible that I need to replace teh light to restore the hole circuit or do I could damage something else. Thanks for yours responses.
