Cleaned the N7, and the rest of them for the hell of it. I also replaced some fuses with copper ones. They really should have came standard. Apparently the alluminum fuses on the copper causes oxidation, which I did not see. Everything works now, including the fog lights. What a pain in the ass. Somebody said those things would fool me, and I guess they did. It still might have been a corroded light switch, but who knows. I'll have to drive around for a while to make sure it's fixed. Despite the aggravation, I'm still glad I didn't go to the dealership or any other mechanic. If anyone is still listening, there are two tail lights that don't go on. I don't even know what they go to. They are the only two lights in the back that light up clear as opposed to yellow or red. If nobody knows I'll just ask the dealership when I go to get my radio code. Thanks again to everyone who offered their help.

Back-up lamps..

90% of Benz power feed problems are fuse connections....but we told you that.
