69 Roadrunner - hazard lights work only if key is on and turn signal is on

[ArtistStan]

I have noticed that when the car is off, for example, the hazard lights will not work. Both turn signals work and all lights are working. In order to get the hazard lights to work, I push the switch on for hazard lights, and while key is turned I push the turn signal in either direction and wala.. the flashers work. This does not sound normal to me. Any ideas? Stan
