Owners Forums for Ford and Volkswagen MPVs / SUVs

We currently live in France and bought a Mark 2 Galaxy Zetec 2.3 from the UK in August 2012. It broke down on us a few months ago when it wouldn't start at all, this ended up with a main Ford dealer looking at it and they said the fuse box was all over the place and then proceeded to charge us a small fortune to put all the fuses back in the right place. We then had our english mechanic do a service on it and put a new battery in and it's been fine until today. This morning we put some petrol in and it just would not start up again. All the lights come on the dash but then nothing at all. We managed to get it going again after doing the classic lets wiggle some wires on the battery and it stopped and started within 10 minutes fine, then after 30+ minutes nothing again and no amount of wire wiggling will help. Again all the lights on the dash come on but then nothing. We ended up leaving the car in the car park and had to get a taxi home.
Our car mechanic is on holiday over Christmas and if we take it to a local garage they won't touch it and they will say it will have to go to a Ford main dealer which is miles away and we have no way of getting it there until our mechanic is back from his hols as it has to be towed on a special vehicle/towbar (french law). In case it is something simple like a blown fuse we have no idea where the fuse box is located as the handbook was not given to us when we bought the car. Does anyone have any ideas please that we may try. Sorry we no nothing at all about cars so you are dealing with complete idiots.
Any help much appreciated.

Many thanks.chrispb,as you say great place to start but sounds to me as if it could be the problem.
Looking at the pictures i would not attempt to get at it myself but at least i can buy the relay and get my mech to do it.
Next problem is the wife can not find relays on the net anywhere so any tips on sites or other names or even part number.
Thanks again.
Tony

Thank you everyone for your help and advice! We got the relay off of ebay (got a volkswagen one as it was cheaper as was suggested) and our french neighbour came and changed it over for us yesterday as our mechanic seems to have temporarily disappeared. It is working just fine, fingers crossed!!!

Once again many, many thanks!
