It doesn't show the speed or the revolutions, but the temperature and gas gauges do work.

I have a 2009 lancer gts. After I had bought the car I started having headlight issues, more so my low beams. They would turn on and off whenever but my high beams worked fine and stayed on when activated. Well after a few years now my low beams won't turn off. Even with the switch off and also my high beams no longer work when activated. So after that I made a little "jumper to be able to use my low beams and turn them off. I can unplug when needed, but now with it unplugged I have an electrical draw somewhere. I've installed a battery cut off switch so I don't wake up the next morning with a dead battery.
Could it be something in my dash not working or could it be the fuse box under the hood? Thanks in advanced for any info
