LED dash lights won't come on

My dash has blue and green led lights. There is a switch wired to it that I can switch between blue or green for the dash. Tonight i went out to start my car and turn my lights on and the blue didnt come on. There’s a dim yellow light though. I don’t think just the blue went out because i tried switching to green and those didnt come on either. I didn’t do this conversion so I have no idea but i’m assuming the its a fuse that went out? If so would it be somewhere along the wires to the switch and if I trace it I will find it? Any ideas what how I can get my dash led back. Thanks
