My radio suddenly stopped working...no lights no clock..nothing. I went home and looked at the manual. My boyfriend decided he knew the fuse. Under the hood he removed the #28 fuse and this didnt fix the problem. Instead my check engine light came on. Can someone tell me where the fuse to the radio is and how to get my check engine light off. Please help... I guess I should add that it is a 2008 Jeep Commander...oops...very important detail.
