about a week ago i picked up a 2000 Passat 1.8L I knew it had a problem with the drivers side controls. reading the forums i found its a common problem with the wiring. I found coronation in the connections and fixed them but after i did that not only did my drivers side still not work but now none of the window controls or the interior lights work. I went over everything i did and checked the fuses and nothing looked out of place. I pulled the map light and checked the wires there. I'm getting 10 volts to the light from the red/black wire and the ground is good. is there a common wire that would effect the window controls and the lights? I'm at a loss for where to go from here.
