OK...I admit it, I must be a moron. I have to replace the pass side bulb and I cannot, for the life of me, figure out how to remove it. The little phillips head screws on the bulb assembly just seem to turn, but don't loosen. What am I missing here? I ran up to A-Zone to get a manual but they were out and I did a search on here and couldn't find anything. Any help would be appreciated.
