Hi all have a 2007 low profile motor home lost power going to rear tail light, front side light works all marker lights working fine lights on motor bike rack working, when o/s rear light tested no power any ideas please

Assuming you have power at the fuse it would just be. a case of tracing the route the wiring take to find the break in the cable

Are any of the lights working in that light unit? Or is it just the side/main light part not working

Odd id have thought there would be

Still your only choice is to try and track the wiring back from the light units

The lights at the rear of an MH other than a PVC, will have been fitted by the converter. This suggests that there will be a junction box(es) located under the vehicle. As I have read of no junction box, and crimped connections pushed into a hole in the chassis, this would be a good item to locate and inspect.
The rearlights on the x250 Ducato are supplied via the BCM (Body Computer Module). I have located and am attaching an appropriate eLearn diagram which was posted previously on forum, perhaps by @rayc.

Yes all works fine

Yes all works fine

There maybe a junction point towards rear nearside, where wiring splits to rear and towing socket. If the trailer rear light works this is favourite spot, if not try at front near battery for the main instalationand trailer fuses.
