12v wiring

[johnsonfe]

i have a 2003 3295 and lost both 12v lights in dinet and couch slideout.. there is 12v undernith till u turn on one of the lights and then it goes away (must be bad connection) the wire is clean and i removed the lower rear panel the wire is clean back where it goes into the rear cap.... 12v is good at fuse panel lights on or off so anyone know how this wire runs is it under the floor or overhead????

thanks for anyhelp...
