Renault Megane II 1.5 dci - electrical problems - boris76

Well I have this car(megane ll 1.5 dci) from dec.2004 about 130.000 miles no special problems except the windows- there is 1.5 y I changed right motor(luckly it was in the guarranty period) and now my wipers does not move almost at all( some kind of slow motion) and also none of the windows are working. I'm affraid maybee could be the cabin unit... (it was a terrible smell of burned plastic - no smoke)while I'm not in the mood to pay..... wonder :(
