Emergency flasher 1967 Fastback

I have a 67 Mustang fastback and since I have it (15 years), I have the following electrical problem.
My hazard flashers dont work. My brake lights work fine and all the turn signals are also o.k.
When I pull the hazard lights knob, nothing happens. But if I then step on the brake pedal, my rear brake lights/hazards come on illuminating continuously together with my both front turn signal lights ( also not blinking, but illuminating continuously). When I release the brakes, all lights go out.
Years ago I changed the emergency warning flasher and brake pedal switch, but that didnt help. I checked the voltage on the flasher unit, and it gets 12 volts (permanent).
I hooked up a new turn signal switch to my underdash harness this week, but also then the problem is present.
I also renewed the front parking light units recently.
Grounding of the taillights is ok.

Anyone has an idea what the problem could be?

Regards, Remco (The Netherlands)
