Ok.....so at one point the signals would just stay on solid with no "blink" and if I tapped on the upper of the 2 flashers they would blink for a while then the next time i tried to use them it was the same thing. The hazzards wont work at all either. I put all new bulbs in and 2 new flashers and they still wont work. The fuse is ok too. I checked. Any ideas? Common prob? Common fix?
