According to the FSM for my 1985 300D (W123), the power window relay is behind the instrument cluster. However, the failure mode suggests a fuse, as none of the windows would work if the relay failed.. Passenger front and driver's rear run off of Fuse F4, as near as I can read the poor image in my CD-ROM FSM. The inside of your fuse box cover will also have this information.
