Headlights Not Working

[grantg]

Hi

 

I've got a C8 2.0 petrol, 2005 model, which has problems with headlights not working.

 

I am fairly confident they were working when we picked the car up, but sometime between driving home that day and a few weeks later, I noticed the headlights do not come on. It does not have auto lights and I have replaced the bulbs (even as far as taking working ones out my other car, the swapping them around again, to no avail!).

 

I hunted around and found the C8 has no fuse for headlights - it's all integrated into the fusebox, so I also replaced the fusebox (original was missing the cover, so would have allowed water ingress which went a long way to explain some issues). Fixed a few problems by replacing the fuse box, but still, no headlights.

 

I have side lights. I have no headlights and no main beams. However, the green light icon does come on, as does the blue icon when I turn the headlights and main beams on, which (I think) rules out the comm unit.

 

So, where to look now? Anyone have any experience of this in a C8?

 

Cheers,

Grant

Get a test meter on the bulb connector and check for 12v. If you have that then it may just need a new earth wire.

what stevestoys says is probably the highest possibility. Follow the harness that carries the current for the headlight. Also check the relays, that is if your new fuse box did not come with working ones in place already.
