Relay : testing, repairing seats relay
The electrically operated seats are controled by a set of four four-pins relays of the 33272D type. Two relays for each seat : one operates the electric engine forwards and one backwards. Typically if the seat only moves in one direction the problem comes from a faulty relay / or connection.
