RESOLVED: 2006 Ford Focus Both Headlamps Not Working Problem

isotonic_uk

Hi All

Hope anyone can help.

Ok so I have an issue with my Focus and I am unsure exactly what has caused it to occur.

Had an issue with my Front driver side dimmer bulb which had blown, so I replaced it with a new one, no problem. That now works fine.

However since I have changed this dimmer bulb both my front 2 main head lamps are now not working. I have checked the bulbs, they haven't blown and I have also checked some of the fuses on the front passenger junction box fuse board.

I have looked at the following fuses and none have blown:

Fuse 37 - Main beam left side
Fuse 38 - main beam right side
Fuse 49 - Lighting control battery supply
Fuse 60 - dipped beam right side
Fuse 61 - dipped beam left side

I am confident this is a fuse that has just blown, as that is the only explanation I can think that would cause this (unless anyone has any ideas of something else).

I went to 2 local garages,told them what I had checked and they think it could be some sort of electrical problem if the bulbs and fuses are ok, but I just dont understand how that could be, all I did was change a bulb.

My question really is

are there any other fuses I should check?
Could it be a shortcircuit somewhere
anything else I could check myself

I can confirm the lights were working before I changed them and all other lights and electrical inside and outside the car are working.

Any advice on this would be most appreciated.

Thanks

If the fuses have't blown and the bulbs are good perhaps you should be looking at the switch

main beam relay?

If the switch isn't faulty then I would try taking out this bulb that you have replaced and see if the 2 lights start working again. It's a long shot but faulty bulbs can sometimes do very strange things.

Fuse 22 (20 amp) powers both headlights.

Thanks for the replies.

Just an update. Even though I was confident that the bulbs on visual looked fine, when I replaced it with a new bulb it all worked.

So it looks like the bulbs had gone at the same time, the only thing I can assume is when I changed the dimmer bulb I interrupted something and that caused both bulbs to pop as I know right before I changed them they were working fine.

Just glad its not expensive bill with a dealer and I can get some cheap bulbs from ebay to resolve.

Hopefully this might help someone in the future.
