My turn signals started flashing faster, I checked the rear and both the turn signals and the brake lights did not work. However the reverse and driving lights did work. I checked both lights and they were ok. The fuse was also ok. The strange thing though, when I had the rear light housing off, I decided to switch the bulbs, the back up/running lights with the brake/turning lights, and the opposite happened. Now the brakes and turnsignals worked, but now the reverse and driving lights did not. Any help?
