A few things to add. Pull the button knobs off of the electric seat control, if you have one on the door, then unsnap the plate from the electric seat control module. Unscrew the seat control module from the door, 2 screws. The black plastic cup behind the door handle should slide forward a little then release from the door. Will also make it easier to disconnect the door latch rod.<br> Other than that it's fairly simple as dave190e pointed out.<br> <br> This is for a 93 190e.
