Xantia Rear Window and Headlight Washer Pump Relay Locations

I've discovered two faults on my Xantia Activa both of which require locating the relevant relays in order to trace the faults. I know that there are relays located behind the battery and below the fuse box in the drivers footwell, but as to what relay controls what function I cannot find any information on.

The first problem is that the electric rear windows work when the switches on the centre console are used but not via the rear door switches. The door switches are not receiving a 12v supply and do not light up as the front/centre console ones do. I've checked the isolator switch on the dash which works OK, but I'm having trouble working out where exactly the relay listed as number 6121 in the wiring diagram, "rear function locking relay" is located.

Likewise, the second problem is that the headlight washers are not working (I know the procedure of requiring headlights on etc). I've checked the pump with a direct 12 volt supply which shows it as OK, but where exactly is the relevant relay (number 5400 on the wiring diagram) located?

I've now managed to find the location of both of these relays.

The rear window relay (the only black relay on the panel on this particular car) is located below the fuse box near to the drivers right foot. On my Activa the relay had been fitted in the wrong slot

The headlight washer pump timer relay is located in the offside front wheel arch right at the top, behind the plastic liner. Its held within a black box which also contains the cruise control relay.

Of course this is the first place I looked........................Well OK, maybe not!

MMmm, I reckon as they went down the production line the man doing the wiring did each one a little differently just for a laugh.
