Fog Light Problems

[Seppele]

Hi all ! After a Rear light conversion (Mainland Europe) the fog light did Not work anymore. The Fog light switch was illuminated, but No light at the Rear end... Yesterday i Fund out, that one of the contacts under the rubber covers was lose. When i squeezed the rubber it worked,, When i let go, it won't work. So i opened the rubber, with a Cutter. As i tried to reattach the positive cable back to it' s Former Place iI caused a Short circuit. After that the fog lamp did Not work anymore. I checked the fuse, it was ok. But the Illumination of the fog light switch was off now and I was unable to Switch it on again. Did I killed the Switch? Or the control box? Any ideas and hints? Many thanks in Advance.
