I have a 01 cl-s and one day when i turned my car on, my display then glowed and turned off, at the same time the clock turned off and the daytime lights at the rear (the brake lights and reversing lights work). I recently had a an amp and two subs installed, and i thought it might have something to do with that but they work fine. I went through all the fuses and there fine and so are the fuse boxes. Help!
-Thanks
