Hi to everybody, I had a problem with my battery so I had to use external help(another car in parallel conection) to start my engine. After that I realised that the rear windows didn't work at all. After 150Km travelling and switching of my car, next day everything was OK. So I put a new battery on, and now none of my windows is working. I checked Fuse (No 17), I try to find Fusible Link as Bruno (e34.net) suggests but nothing( I own a 520i M50 91'), I checked all the relays for bad connection still nothing...Any suggestion please?
