More Xantia Electrical gremlins

Are these likely to be connected in several senses of the word.
1998 Series 2 Xantia 2.1TD
Heated rear window and heated mirrors not working, heated rear window dash warning light not on. Relay heard clicking when heated rear window switch pressed.
Also, cigarette lighter and auxiliary 12V supply socket not working.
Looking at the Haynes manual suggest that the heated rear window and mirrors and the cigarette lighter do not operate on the same circuit. No mention of where the power for the auxiliary socket comes from.
Fuses under the dash related to heated rear window and cigarette lighter appear to be OK.
Before I dive in with the multimeter this weekend, does anyone know where the heated rear window relay is located and do people think I just happen to have 2 faults or just the one?
Thanks in advance
Rory

More likely to be two causes than one, I'd have thought. I've blown my cigar lighter (auxiliary socket) fuse many times just by plugging my phone charger into it - it seems to be especially vulnerable to getting short-circuited if you don't push the thing into the socket absolutely straight. I've also found that when the cigar lighter goes off, so does the light in the glove compartment. I'd have another good look at those fuses if I were you, because I've seen fuses that look absolutely fine but don't in fact pass the current.
I wouldn't think it was a problem on the ignition switch, because the cigar lighter works at any time whereas the ignition needs to be on for the heated window to work. (1995 1.8 16v.) But it occurs to me that both the hrw and the cigar socket need to pull a fair few amps. Could it be something as simple as an earthing fault?

Does the radio work? its usually fed from the same supply as the lighter.

Don´t forget to check the ground connections...

Thanks for the input guys.
Just been out to the carpark.
Radio works. Glove box light works. New discovery, hazard flashers don't work.
Regards
Rory

I like my Xantia in almost every respect, but I don't expect (in what was advertised as an executive car) electrics to fail as they invariably have [:(!]
The fan heater is the worst IMHO, whilst I have experienced lots of electrical niggles. The abs sensor design is crud also. The way they keep failing is criminal.

Interesting to hear your ABS sensors fail regularily on a 1998 car. This does not seem to be a general experience so I start wondering about installation or other problems - or indeed if they were faulty in the first place.

Mine's 98: no problem with ABS sensors at all yet (crosses fingers)[:)][:)]

Update on the non working heated rear window, cigarette lighter/ auxilary socket and hazard flashers.
I now conclude that these must all have the a common 12V feed. By bridging 12v direct from the battery to the fuse box with a flying lead these items all work.
All the big "you must go to Citroen if they blow" fuses under the bonnet are OK so now its a case of follow the wires.
Does anyone know how to get to the back of the fuse box in the passenger compartment, it looks like it could unclip and drop down but I haven't work out how.
Regards
Rory
