Detail the interior

The power seat control switch is a known trouble spot on the W124 as they get older. The nice thing is it is easy to change out and does not require removing the door panel.

The power seat control on the driver side consists of the switch, trim cover piece (yellow arrow) and plastic control pieces (red arrow).

Use your trim removal tool and carefully pry the plastic pieces off taking care not to damage the trim piece or door panel.

Carefully remove the switch from the door and turn it over. Remove the two electrical connections (red arrows). The connections are unidirectional and will only fit in the proper receptacle so you do not need to mark them. Installation is the reverse of removal.
