Which fuse controls the front seat lighter? Which fuse box is it in?

Hi, I was having the same prob. I went to a Mercedes dealer. They advised me that the fuses for the Radio & lighter in the front dash board compartment are located in the fuse box that faces forward under the rear right passenger seat. I bought the recommended fuses from Advance Auto Parts and tried installing them yesterday. In the process, I dropped one of the original fuses inside the box. I do not know what was the amperage. My car is dead now and I may have messed up the computer electronics or something. Please, please do not do anything to solve your small problem and get into the huge problem I am in. Please call me at 248 760 7789. I want to try and help you avoid the pitfalls I fell in. Moreover, please be a little patient until I definitely solve my problem, before you attempt for any repairs. Thanks and best of luck. Syed Baghdadi. P.S: Please check posting on Cargurus, I posted yesterday.
