Please help. Headlights cannot be turned off with switch. Bright/Dim switch is working. Headlights still on when switch turned off and key removed. They`re still on with the headlamp relay removed. Having to leave battery cable unhooked. Anyone have any ideas. Thanks in advance for any info and replies.

 

Try removing the DRL relay in the underhood fuse block. It could be stuck in the closed position which would cause the headlights to stay on all the time.
