Back to this thread again after removing several door panels and fixing a few doors.
I did notice that the OP's DIY does not include removal of a clip I encountered working on a 1987 W124 300TD.
Removing the buttons for the seat switch to then remove the trim over the switch and the Egress lever, it is also necessary to remove a retaining ring from the center pin of the seat control.
I modified the OP's pic to show the location of the clip in question.
Again, great write up, thanks for sharing.
Someone mentioned getting replacement J clips from the dealer. Is this possible?
