Pictures would help a lot. But is sounds like you are describing the standard turn signal set up. Are you using the bulbs with two elements? I assume the rear turn signals are working, right? If they are, that eliminates the flasher unit, if not, it could be the flasher unit. You said they have power, how did you determine that? Does your car have side marker/turn indicators in the front fenders (I think they do)? If so, those may be bad and preventing the front ones from working because they are in series with each other, check them too.
