Flashers stopped working

On my drive home from work today, my turn signals stopped working. My hazard lights work, no bulbs are burnt but when I flick the turn switch, nothing happens. Is there a separate relay for flashers? I can't check it out till tomorrow, it's raining hard outside.
Thanks
Mike

Should be the Relay. Its a combination for emergency and turn signals. Mine worked for the turns-not for the emergency.
On '76 onward cars, the relay is located just underneath the instruments. You get access from the luggage compartment.

Thanks, although I finally checked it and it was a burnt fuse.
