the drl fuse you will have to talk to the dealer to find out about, the drl switch is to have the lights on when key is in switch, if you can find it pull the fuse and leave it out and the head lights will work norm.
Nissan never made daytime running lights for this vehicle. Its possible that your switch knob on the side is broken and the control switch behind the actual platic is stuck on the on position, but your saying your high beams are on. The little piece of plastic that is postioned to pull your high beams off might be broken as well. If i were you id check a local junkyard for something simple like that.:idhitit:
