I have a 2014 G63 and the accordion boot between the driver door and body has torn apart and has to be replaced. I removed the door panel and unless I"m missing something it just didn't make sense that the repair should be done from there since I'd have to fish an absolute mess of wires through the boot.

Has anybody changed this accordion boot and did you disconnect the wiring harness in the kick panel? Any advice on the best way to change this out would be geatly appreciated.

 

Correct, you need to disconnect all of the wires at their harnesses in the door, fish it all out. They're all zip tied in as well.

Probably a lot easier on the early trucks.

 

Thanks for the reply. I am going to update this thread just in case somebody else might need this information in the future. As I said before I was needing to change the rubber accordion boot that protects the wiring harness in between the front driver's door and body on my 2014 G63 AMG. I initially removed the inside door panel and when I looked at that scenario something told me this was not the correct procedure. I just couldn't imagine Mercedes would have done the design this way for a number of reasons. I then reinstalled the door panel and slept on it.

The next day I removed the driver side kick panel. I simply flexed the rubber perimeter seal off of the kick panel and gently pulled it toward the rear of the vehicle and it came right out. The kick panel didn't have any clips or fasteners, and I did not need to remove the door sill. I then spotted a fairly decent sized hole in the sheet metal directly behind the kick panel and it was covered with a white plastic that was glued in place with a black adhesive. I used a 5 in 1 paint scraper tool and gently scraped under the black adhesive taking care not to stretch or damage the white plastic. I ended up scraping loose 2 sides of the white plastic, the side toward the rear of the vehicle and the bottom. This allowed me to fold back the white plastic thus exposing the front half of this hole in the metal. I then observed a light-colored foam wrapped around electrical connectors and another small electrical connector next to this group. I grasped the wiring harness in between the door and body and gently moved it back and forth and when I did this it was obvious that the foam wrapped connectors and single loose connector were the same wires that went through the door jamb and into the door. I gently tugged on the foam and the single wire connector and was able to pull them out of the hole where I could more easily work on them. I then carefully unwrapped the foam where it was stuck to itself and removed it from around 2 blue electrical connectors. I then disconnected both blue electrical connectors and I disconnected the small single black connector. I then cut a piece of twine about 2' long and tied it to the disconnected wires. I then pulled the disconnected wires out of the body and of course the string came through also. I then untied the string and left it laying through the hole from the inside of the vehicle and out through the hole in the door jamb. Now I simply slid all the wires through the new accordion boot and then I used the string to gently wiggle and pull all of the wires back through the hole in the door jamb and back through the hole in the kick panel. I then installed the black rubber accordion boot which i had to wiggle and squish and work at to get the small cut groove fully nested on the perimeter of the hole in the door and the hole in the door jamb. Once that was finished, I just plugged the connectors back in, re-wrapped the foam back into place and it stuck to itself as good as new. I then reinstalled the kick panel and tested all of the switches in the door and the door speaker to make sure everything was working fine, and it was. The entire repair was extremely simple and took less than 30 minutes. My Mercedes dealer had quoted me 2.5 hours labor for this job at a price of about $550.00 and the service writer told me it was a real headache having to take everything apart inside the door. Well, I now know it's a 30 minute super easy job and there is no need to even touch the door panel and if you think about it Mercedes designed this for a reason. The assembly line process and also in the event the door would need to be removed this design is what makes the most sense by far. I looked everywhere online and also at YouTube and the only thing I could find was a door removal video on a 2022 G wagon which didn't answer my question so I hope this post might save somebody a lot of money and time in the future.
