Front drivers door electrical issues

[poolietim]

Hope someone can help.

Electric wing mirrors have stopped working, electric window controls on drivers door won't operate any of the 4 windows, although the 3 passenger windows all work from their own control.

Plus the drivers door remains unlocked from central locking being activated.

Anyone experienced this and have the solution please??

welcome to the drivers door loom !!

the wiring in the rubber gaiter from door to body is renowned for breaking, read the tech section so you can do it step by step. assume you need a few hours spare time, dry weather and a good soldering iron, cable & heatshrink tubing.

Thanks for that.

I've also noticed that the external fuse box in engine bay has some evidence of being melted and scarred by one of the connections / cables.

Has this any connection to the other electrical issues or something seperate?

Fix/replace the fuse box in the engine bay first details here https://www.fordmpv.com/smf2/ford-galaxy-reference-library/battery-junction-boxauxiliary-fuse-box-repair/

The second wire down feeds the fuse box in the main cabin so a damaged connection here can cause low voltage on the components fed by the fuse box and cause all sorts of issues.  It may cause some of the issues with the drivers door, but unfortunately I suspect it will turn out to be one of the door or hatch to body harnesses. Don't just assume it is the drivers door harness  (though that is most likely) as faults/shorts in any of them can mess up the whole system they are connected to

With regard to your fuse box, if you catch it early then you may not need to replace the fuse box, just remove and replace the corroded connections. You'll need to cut the corroded bit of the end and then I used heat shrink to cover the crimped connection. Just be careful re tightening connection as the first bit to melt is usually the bit of plastic that stops the locating clamping washer spinning and it's easy to end up damaging the fuse with enthusiastic tightening.
