I have changed the electronic flasher and they still won't come on

Is this a GM vehicle? If so, read this post

Turn Signal problems on GM vehicles (http://www.ricksfreeautorepairadvice.com/repair-topics/electrical/turn-signals-problems-on-malibu-impala-alero-cutlass-grand-am-monte-carlo-saturn-vue-chevy-s-trucks-chevy-t-trucks-corvette)

The link shows Hazzard a likely culprit, I would also suspect the signal head.
Turn signals and hazzards are on different fuses. Turn signal is Ignition switched and Hazzard has a constant hot.
Those 2 items(hazzard switch, signal head) are common to both.
