Is it Flasher relay or Hazard Switch?

[Poderosso71]

This is regarding my 72 tii, now i know the Hazard button is broken,the hazards stay on all the time unless i presss the button in,currently a tooth pick does the that job.Once the button is in,the hazards are off. However,the turn signals dont work at all. From searching around,i found out that turn signal flasher relay and hazard switch are connected..Since only the hazard button is broken and not the hazard switch itself,i suspect the turn signal flasher relay is at fault, however i have so many other things to fix that i really dont wanna spend money on something i did't even need in a first place. Could a broken hazard button cause the turn signals not to work?...yes i have checked the fuses and cleaned the lights/conections with no results..

Any help is greatly appriciated..

Do a search on the flasher relay. Mike Self had some success in cleaning up and resurecting his.

The Hazard switch ~can~ be taken apart. The inners of the hazard switch operate like a clicky ball point pen. Usually, the fault is that the flat spring that holds the pin weakens and the pin pops out of place. This allows the plunger to eject. I've repaired a few and they seem to last for several years. However, if your car is parked for the whole day or more, and the switch pops out, your hazards will go on. You'll usually find a dead or very low battery. Sometimes you might have ~just ~enough juice to crank the motor once.

The replacement hazard switch is slightly different in the cosmetics from the original one. But it is plug and play, and should last many years.

If you are on a tight budget, I'd give the rebuilds a try. Just make sure you already own a set of jumper cables.

Jumper cables are in the trunk,along with many other things if in need.....

I will take the hazard switch out,and see where this takes me..

Thx for your help Steve.

Then there is the school of thought that were you to 'repair' the switch, and it did indeed last several years as the previous reply suggests, what are the prospects that the replacement switch will still be available when the repaired switch finally gives up the ghost, the car is now 45 yrs. old and a replacement is NLA?

It may be prudent to consider biting the bullet now and replace it, repair the old switch as shelf stock, if ever needed.

The answer will depend a great deal on what your longterm plans for the car may be.

Cheers!

My turn signals weren't working, found the hazard switch was broken. Replaced it, turn signals now work.

That's how I ended up with three hazard switches for my car. The new one is in there right now until I have bench time to diagnose the two originals.

I would spend a few min fixing the emergency flasher its not hard. Then you can diagnose the turn signal problem without any problems. Once I did one I fixed all three of the ones I had.
