The Flasher Relay is more than likely defective. Some vehicles have 2 relays. One for the turn signals and one for the hazard lights. Replace the Flasher Relay for the turn signals.

There are separate flasher relays for the hazard lights and turn signals. The flasher relay may be out on your blinkers. The relay for the hazards is behing the fuse box. The relay for the blinkers is behind the lower dash panel to the right of the steering column.
Some vehicles has a flasher relay for the turn signals and another one for the hazard lights. Are you sure you replaced the correct one?
Check the fuses and the flasher unit.
On a 2003 Chevy Monte Carlo LS there is a turn signal flasher unit under the dash on the driver's side that will cause the hazards and turn signals not to work properly, if it is no longer functioning. This is a plug in that has three prongs, and can easily be changed by unplugging it and plugging in a new one.
Check to make sure that ALL turn signals are working Could be flasher
Bad switch? Bad hazard flasher?
