Hello, i drive a 2007, 5,4l V8, XLT-4X4 Ford Expedition in Germany. We changed th turn signals in Germany like th Europe standards. The back white ligts are now the turn lights. We disconnected the brake lights from the back turn lights so the brake lights are only using for the stop and brake lights. I cahnged the white flashes with yellow flashes. It works very well for 2 years. But yesterday happens. The left turn signal not works. I measured the power but measured nothing. Fuses are o.k. relay are working also good. The back turn left signal for the trailer are working and i connected it with this wire. But if i pushed the brake, now it's burn also the left turn signal. On the back left turn side their are power awailable bujt on the front side their are no power awailable. What can be the reason? Who can help me? Excuse me for my english.
