The problem persist and best alternative is the dealer but due to weather and bad traffic (have to cross a bridge which now is under repairs and chaos to cross) I always postpone to make an appointment. Trying to remove the big side panel by the loading area is impossible for me, pulling up and away from the wall it feels I will damage it.
However I noticed when the rear seats are up the noise almost disappears or not as frequent so I now believe this noise is related to the rear seats recline mechanism. Reading on the web they say the 2 motors under the rear seats are connected to the switch on the drivers side rear panel via a "tunnel". I also noticed there is a steel cable per motor which goes towards that rear panel. If the "tunnel" is metallic then the noise I hear is that, a steel cable banging on the walls of metal.
To view the motors mechanism properly under the rear seats I am able to lift the one pc seat but there are cables attached to it and before removing the seat I should first disconnect these cables. Is there any schematic available of all wiring / mechanism involved on the 2 reclining motors? (2016 Edge Titanium)
Thanks
