mot failure..fog lights???
i replaced the back light units on my 96 xantia for ones from a newer model everything works as it should except for the fog lamp section,does anyone know if the bulb holder section different between models or is it just more likely to be a wiring problem?
its now got the lighter version in

Have you got a towbar? Citroen lead expects you to have a lighting socket with a switch in the pin for the foglight. Power for foglight is diverted to socket. No plug in socket - pin out - contact made and car foglight fed via towbar. Plug in trailer, break contact - car lights go out.
Marvellous if you use the correct socket - otherwise find the relevant wire and bridge it using a couple of bodgelocks and a short bit of wire.

What I am saying is that if you have trailer lights fitted using the proper lighting adaptor cable you may have problems. Bar removed but lights not altered - problems. The trailer lighting adaptor is a plug that fits in the nearside rear light.
If your car never has had trailer lights then this is not your problem.

Not sure about places in leicester itself as I'm in loughborough. I know of charnwood-cars and eurocars, both claim to be citroen specialists although personally have never used either as I diy.
If you're able to get over this way in the evenings I don't mind having a look at it for you - free help & advice etc.

Jake,
I'm pretty sure that if there's a relay under the bonnet that would be for front foglights.
Rear fogs only work when the headlight are on, the light on the switch should illuminate to confirm when they are on. - Can you tell us whether or not this light is coming on?
I'm at work at the moment and haven't got the wiring diagrams to hand, but potentially the problem could be either rear fog fuse / headlight switch / foglight switch / rear end wiring.
The reason people have mentioned towbars is because when towing a caravan the foglights would reflect off the big white box and distract the driver. The wires for the foglight go to a 4 pin connector behind the carpet near the right hand rear light - there should be two grey wires linked together with a small loop of wire (green on my car) this is the link wire that gets cut when installing a caravan socket. Find this connector block and check for voltage (multimeter or 12v light bulb will do).
Assuming you have power here; the wire returns behind the carpet, along the side of the parcel shelf and up behind the panel where the rear seatbelt is attached - into the bootlid. Check here for a break in the wire as it bends each time you open the boot.
The wires inside the bootlid go to one side first, then they run to the otherside by a flat ribbon type cable. This is the easiest place to test and should be your starting point, before buying any more rear light clusters...

some xantias suffered with faulty wiring,i have done a couple where they have lost there feeds for the rear fog light.there is a loom that runs along the drivers side sill/floor area.they tend to loose the feed near the rear section of the loom where it disappears at the quarter panel.if you have a power probe you should be able to trace the feed etc.

first off excuse the timing of my responses,i work nights...... wiring might as well be spaghetti to me,Stewart i had the radio out recenly which is quite near the fog light switch which is illuminated if i knocked a connection off would it still be able to light up? the only other thing i changed was i switched the alarm on under the bonnet and it seems to work perfectly...not over sensative like some except for the obvious when it rains
Andy if i dont manage to get it sorted is the offer of a trip to yours still on?
