Smile Window problem 129 series.

I have a 320 SL, '96 year of the 129 series. The problem I have is that my left window will open but not close. Checked out the window motor (ok) and checked/replaced the window switch (ok). I want to know where the electric from the window switch is send to, to let the window go up. On the information I have with me it looks like from the switch the wires are going to a relais (spannungsversorgung in German). Can somebody tells me where this can be located for the left window maybe ?
Ofcourse because of this my soft top doesn't work at all as well. If this relais is not the problem, should I go to the next level like the main box under the seat ?

The relay is in the soft top controller. Under the right rear storage compartment.
There is a seperate relay for each window.
Resistance is Futile.

sl window problems

It sounds like you are further along than the following suggestion. After years of window stoppages with porsches and mercedes (300d,300sd, 300sl), It is almost always the poor fuses. The fuses your looking for are at the back top of the trunk. Most times you can just rock the fuse and the problem goes away. It is certainly the cheapest and fastest way to start.
