It's not high and low beam, it's the dash lights that are dim. I've hooked up many aftermarket radios but never knew it was a no no to hook up the dimmer/illumination orange wires in a '01 civic. I googled it and seen many others with similar issues like mine but nothing exactly like the issue I have.

All the dash lights work, they are dim though. The radio lights work but they are even more dim than the rest of the dash lights. I have check every single fuse under the dash and in the engine bay. The dim controller does not work at all now. I'm guessing that's the issue and from what I read, the dimmers circuit board is in the instrument cluster. Some can fix it, others can't.


I will probably end up buying a used instrument cluster off of ebay, they are not expensive. Hopefully that fixes it since everything else works.


Oh, yes, the brake lights work.


Ted, I think you answered the wrong question...I mentioned nothing about the battery or the low/hi beams

Thanks for using FixYa!

Hello manchie...You should have a dash light dimmer switch..remove it from the dash. There should be a 3 wire plug on the back side with a Red/Green, Green/red and black wire. Jump between the Red/Green wire and the black wire and see if the lights come on. If they do, it probably has a bad illumination controller.
Good luck and i hope this will fixya up.

did u know that they make a harness for your car that plugs into your factory harness and then adapts to your aftermarket radio? for the lights, you have blown the interior light fuse, it may be the same fuse as the cigar lighter.Below is your radio wire colors and what they do.
