It is built into the hazard switch. If the hazard switch is on the steering column, replace the turn signal switch. If it is in the dash, replace just the hazard switch.

I think you might have a separate flasher for the turn signals under the dash. The turn and hazard flasher would look alike. Turn you hazards on and find the flasher for it under the dash. You will probably be able to feel it working and hear it clicking. The other flasher under the dash is for the turn signals. Try replacing that one. I think it was in later years they began to combine the two into a single composite flasher.

Your vehicle has 2 flasher relays. One for the turn signals and one for the hazard lights. The turn signal flasher relay is located on the drivers side, under the dash, mounted on the drivers (Left) side of the steering column. The hazard flasher is mounted on top of the steering column. Do not get them mixed up.

change flasher relay in fuse box

Yes your right the emergency flasher switch is the flasher and located in the middle of the dash and it has a triangle on it with a point up and a ! in the middle. It's dark red in color and when depressed lights up red and flashes ( if it's working like it's supposed to ) If the fuse for hazard is blown the flasker won't work on turn singal either. The fuse for the hazard is hot all the time and the turn fuse is only on with the key. You might find that when you find the button and push i thaqt the turn signals work normally and after you find why the flashers doesn't work on hazard then the hazards will work too.
with the hazard switch poped out of the dash ( it just pries out) it'll have lot's of wires one will be hot all the time and another will become hot when you turn the key on. the other wires go to the turn signal switch. If you find that the switch works fine and it still does flash on turn but it does flash on hazard with it on as a hazard go around and look at all of the lights. They have to work on both the frontand the back and the indicators in the cluster ( speedometer head ) If they all work and are bright ( not dim light the running light) The hazard switch is bad as it's the flasher is made into it.

If the lights come on but just do not flash, replace the flasher relay. Your Thunderbird has 2 flasher relays. One for the Turn signals and one for the Hazard lights. The turn signal relay is located Front seating area, driver side, under dash, driver side of steering column, mounted in lower corner of fuse block . The hazard relay is located Front seating area, driver side, under dash, driver side of steering column, mounted in rear of fuse block. Replace the one for the Turn Signals.

the hazard switch above the radio is your problem. if you put on your signals and they don't flash turn hazards on then off and they will flash. (changing this *** will fix your problem

Iam an ASE Certified mechanic and i had the same problem with my 99 century and i wasnt able to drive at night. After hours of testing wires we came to the problem. Its the turn signal switch assembly which is tied into the hazard switch on top of the steering column. Its all one piece with a 3 foot long wiring harness attached to it running down the bottom of the steering column and going underneath the dash. The least expensive place i found the part and had it in stock was my local Auto Zone and still the part was $200.00.
