What year/make is the vehicle? Something is suspect here. If the blinkers in the rear won't work, then the ones up front won't work either because there won't be enough load on the system to cause the flasher to work. What I think, is that you probably have one of your 1157 bulbs put in wrong and it is screwing up the system in the back. In fact, if you hit the brakes, I bet the front driving lights are illuminating. Get somebody to watch.
