Hi Guys
Have just foind a problem with headlights not working. So am hoping for a quick few pointers before I get onto the detail of wiring diagrams etc.

Here are the symptoms:
Dipped and main beam headlights do not work.
Sidelights work and the flaps do open.
Headlights will flash normally using indicator stalk.
In checking all systems found that hazards don't work and when hazards switched on indicators don't work, realise that may be logical.

All fuses checked and ok.

Without consulting wiring diagrams etc I would assume either the headlights are not receiving power from an ignition live (but this would mean hazards are a separate issue) or an earth problem. The latter being a guess as may be linked to all the bad weather we've been having.

I've initially discounted a relay as couldn't see how this could explain dip and mains not working.

I can go through trouble shooting routines, but the reason for the early post is son gets married on Saturday and is using the car, so am short on time and looking for a quick steer. My starting point will be earth near battery and headlight switch.

Thanks
Nigel

I agree, sounds like a dead stalk.

Will do thanks. Have ruled out switch as there is an ignition live output to relays.

If you car has dim dip then there are several relays involved, from memory a white one and a blue one.

May be a daft question, but where are the headlight relays. According to Haynes they are not behind fuse box.

Andy, to save me searching as I'm short on time and daughter using car at the moment, where is the column earth?

Also looks like the hazard problem is a separate issue. If I play with the switch they work. May be catching the shroud.
Thanks
Nigel

Before dim dip was installed there are no relays for the switch, the switch
feeds the headlights directly via the fuses.

Dim dip introduced 2 relays that aren't in the main fusebox, they are either
in holders (blue and white to match the relays) that clip to the side of the
main fusebox or i seem to remember some where clipped onto the door pillar
next to the fusebox.

The 2 relays connect the headlights in series if the sidelights are on and
the ignition is on.
Removing 1 of the 2 relays disables the dim dip but i can't remember which.

Jim

Just incase you've not got them, here are the lighting circuits.

You can see the extra wiring for the Dim dip in dotted lines and relays
11,12, 13 & 40 ( seems there were 4 added not 2 !), 11 and 12 are the ones
external to the fusebox.

If I recall correctly, I think I had this happen on my 2+2 aswell. 

This one relay worked the head lights, Hazards and horn I think. 
The thing I remember is it was the relay that was twice as tall as the other relays. 

Hope this helps.

Thanks for the inputs. Jim's explanation was a big help. No headlight relays!! Rechecked switches and am pretty sure the wiper/ headlight switch is faulty as there is no power on the black white wire between this and the indicator stalk switch. I assume this wire is the headlight on wire that the indicator stalk then uses to select main or dipped. Would appreciate someone's confirmation. So presumably the headlight flasher gets its power from the same live as the indicators.
So next question is does anyone have a spare switch they wish to sell?
Thanks
Nigel

Nigel,

I had the same problem, opened the switch and found a piece of plastic that
had broken off.
After removing it the switch worked fine again.
You can open the switch at the back.
Cut away the 4 molten holding pins - flush with the back.
How to keep it close after the repair is the question, you could use epoxy
or some kind of glue - in the 4 holes only so that you can open it again in
the future if needed.

Success
Hans
