Hey guys. So I have a 2005 impreza rs and my speedometer, rpm and whatnot lights aren't working(check engine and all that still work). Also my dome light doesn't work when the doors are opened, but works if I turn it on manually. My auto door lock button is also not working, as well as the console lights and shifter lights. All of these went out at the same time, right when I installed my hella horns. I've checked every fuse and they're all good. I also replaced the bulbs in the dash cluster. Unplugging the horns doesn't fix it. Can any of you help me out here? It kinda sucks not being able to tell how fast I'm going at night lol. TIA everyone.
