w123 power window prob.
 

just got this 84 200 euro sedan from my father, it was parked for a long time, so i did every thing and took it to the work shop and spent a month+ all my savings on it , had it 60% finished and now awaiting to instal suspention parts and final body touches, the passinger side window just stopped working, at first it used to roll down but wont head up to close the window, and now no up or down movement at all , i tried switching the driver side key with the pass side, the passenger side key rolled the drivers side window downwards only so the up function on it is not working , but the driver's side key did nothing on the pass. side window, but it works just fine up and down back at driver's side !! could it be the wiring ?? i guess, and how easy can i "DIY" the problem because the car is getting really dirty and un secured! any help will be appreciated.

Im guessing the 200 has the same 'in the console' window switches the 300's do.
I just swapped a switch to get my 300D window up. One of the contacts on the old one physically broke.
