Hi everyone, Help please. Power to my passenger door keeps going off, no windows, lock doesn't work, wing mirror indicator stops work, then they will all work for 10 minutes then all goes off again for days on end 😩😩 anyone had a similar fault?

Thanks
 
Check the wiring in the cable trunk to the door not unusual to find one or more wires with cracked insulation or completely snapped
 
You might be lucky and be able to see it is broken.
 
Often in the loop between the car body and the door
 
It's also possible that the problem is with the wiring loom to the driver's door. The functions of the passenger door are often operated by controls on the driver door, some of which are duplicated on the passenger door and the driver's door loom normally suffers much more flexing over the years than that of the passenger door.
Depending on design, there might also be multi pin plugs and sockets in the 'A' pillars, where the door looms plug in, and these can suffer from corrosion if water gets in.
