• How much of a job is it to replace the wiring that sits in the little hangar/loom thing in a driver's side door? It's a Skoda yeti. I took it to the garage last year and they didn't do a great job tbh and the issues are back (basically driver and rear driver side door don't have any electric function so aren't locking and no electric window /wing mirror etc). Last time they cut into the rubber shield and patched the wires that had failed. I suspect I could get in there and repatch them myself easily enough but I wonder how much of a faff it is to replace that entire wiring section and harness with new/nos? I could ask them for a quote to do it properly but wonder if it's DIYable? If it's just dissembling the door I think that sounds ok (so long as I'm not going to bollocks the airbags or something) but for the part that connects into the chassis of the car, how deep do I have to delve?

  • Does the door loom have a plug at the 'A' pillar? if so undo that, remove the door panel and pull the loom through so you have mor room to work on it.

    The best way is to cut out the broken section, preferably removing each connecter and fitting a new connecter to a new wire and solder that to the good part of the door loom so that the solder connection is not in the moving hinge part of the loom where the brittle solder will break again.

    Best practice for a beginner is do one wire at a time so you don't end up crossing circuits

    Also best to renew that grommet they have cut in to or water will get in and corrode any plug in contacts or even short circuit some circuits when it rains.

  • I was hoping to get away without soldering anything and replacing the entire pack of wires with a fresh set - ideally with the updated shape with extra wire length - i.e. go from this:
