Location of Electric window diode

Hi All
My electric windows stopped working. I found they work with the doors open and this is to do with the little switch on the door pillar (they stop again when I press the switch, always wondered why there were 2 switches there!!).
Following the Haynes wiring diagram the only other suspect items in the circuit are the relay and a diode. Can anyone tell me where the relay and diode are located? All fuses are fine.
Car is 1987 300D, 124 type. Thanks in advance

ON USA models the power Seats have a diode that allows operation with the key on OR door open with key off, BUT the windows here(USA) can't be operated with the key off.
