I read another thread on here about disabling DRL's on an 03 Cavalier, did everything they said, cut the dark blue wire and ground it and there shouldn't be any drl's when I did it, the lights were always on, even when the actual lights were not on, so I took the wires out and connected the dark blue wire back and threw a quick splice connector and then grounded it, now the drl's are still working and now I have no cluster lights. Need help
