Well it would help if you supplied a little more info . Like make , model an year vehicle . So we could look at a wiring diagram to see what all is involved in controlling the hazard lights , could have a electronic module - BCM controlling them . Hazard switch may be just a input to the module .

Why won't the headlights turn on?

This vehicle has problems with the multifunction switch AND the hazard light switch. Try turning the switch on and move the hazard light switch back and forth up and down. If that's not it, I'd look at replacing the MFS. There is a TSB on the MFS, but typically for the brake lights not working. Look in this to go over the steps to take to diagnose also.

How do I locate and remove the TURN SIGNAL FLASHER IN A 1998 NISSAN PATHFINDER

Remove the clamshell, the semi-circular shaped trim cover that sits on the top of the steering column just in front of the steering wheel. The hazard flasher button protrudes through this piece of trim. The clamshell can be unseated by prying gently on the edges with the screwdriver. Set the clamshell aside.
Remove the multifunction switch retaining screw with the Philips screwdriver. The screw is located in the body of the switch, holding it to the steering column.
Disconnect the wiring harness from the multifunction switch by hand and lift it out of the steering column.
Put the replacement multifunction switch in position and reinstall the retaining screw with the Philips screwdriver. Connect the wiring harness back into the body of the multifunction switch.
Place the clamshell back in position, making sure the hazard flasher button protrudes through the hole and push down gently until the clamshell snaps back into position. In some model years, you may need to coax the retaining clips on the edges of the clamshell into the seats on the connecting trim panels.
Test the turn signals, head lights and hazard flashers before driving the Expedition.

1999 ford f 550 turn signal and hazard lights are not working. fuses are good.

I am not familiar with this vehicle, but I am confortable with wiring diagrams. I pulled the electrical diagram for the model year 1999 HD/350/SUPER DUTY (which would include your F-550). I would suspect the hazard switch in your multifunction switch/arm/wiper lever. It is the only common thing between the 2 systems, and both are wired through 2 different flasher assemblies through 2 separate wires to the multifunction switch/arm. In fact, the hazard lights are a hot battery item and bypass the turn signal switch for the front turn signals as well as the indicators in your dash.

Try to check if your stop lights do come on when you hit the brakes... if they don't, your problem is really with the hazard switch within the multifunction switch/arm.

I do not know if this switch can be replaced separately from the multifunction switch/arm, but from what I found surfing the net, the whole thing (multifunction switch/wiper lever) goes for about 50$. There are some DIY on the internet to replace the assembly, but it would seem it can be a bit tricky to replace for someone not familiar around the steering wheel portion.

Hope this helps.

1992 Ford Ranger Turn signal/Hazard light issue

Can you just check to make sure the ignition key switch is not staying over to far and not backing off when you try to start it. I had a truck that did that and it messed up my turn signals until I brought the key switch back a little after starting it. Just a simple idea. Be kind with your rating for me. Raz
