So two days ago my 99 z24 daytime running lights was working like normal then the next morning they just randomly quite (and the drl light is also flashing now) so I've replaced the relay and blubs but still nothing(no lights and drl light keeps flashing). The regular headlights, fogs, and brights(which are the DRL blubs ) all work normally
anyone else have this problem or a cure to it?

id like to know too, mine have been doing the same think for about 2 weeks now..i thought mine was because my brights went out but i changed bulbs and it still happends..do urs flash really fast at first? mine when i put it into gear the dash light and the headlights flash than the drls dont come back on

yeah it flashes fast at first then slow(er)

yea iv messed with mine but im stumped..mine started acting up when i took my headlights out to clear them, then i noticed the bright on my pass. side was out so i replaced it and checked my wiring but i havnt found anything

i checked everything i could and nothing my DRLs stopped working Saturday but was working just fine all Friday i did a search and some people online said it could be related to one of the two grounding spots right under the battery i tried to clean them with no luck but then again i was rushing because i had to get to my college

Check voltage to your lights, and also resistance to ground for your lights. Our lights are a switched ground, so when low beams should be on, you shouldn't have continuity to high beams and vice versa.
