It's the same bulb for dipped and high and they both still work on high. Just had a multimeter on the connections and there no current going to the bulbs when they're on dipped. Switch is working but the drls stay on which makes me think a relay isn't doing it's job somewhere

It's an odd one, but high beam must be on a separate circuit as you can flash without having dipped on.

Hi all - long time lurker here and hoping someone can help. My wife's 2014 Monte Carlo has developed an odd fault with the headlights. Neither dipped beam is working but both high beams are. The car has the older style (but black) headlights so has just a single H7 for dipped and high beam. When I turn the light switch from sidelights to headlights, the green light comes on the dash so the switch is working, although the DRLs in the foglight housing do stay on. The indicator stalk works for flash or constant main beam. I'm stumped as to what's causing it. I've searched for other threads but they all suggest the stalk or switch could be the problem, but that doesn't tie in with my symptoms. Aside from the switch activating the icon on the dash, I'm assuming it should trigger a relay somewhere to illuminate the bulbs, so could this be the problem...and where can I locate it? Any advice would be massively appreciated! Cheers
