I took my Fury for its annual safety inspection today and the inspector passed it but mentioned that my hazard flasher lights were not working. He was cool and told me to get them working but didn't reject me. The lights haven't worked in a long time but I want to find the problem and fix them. I think I replaced the flasher before but that didn't solve the problem. Is there a relay in the hazard system which could have failed and if so, where is that located?
I'm going to do a process of elimination task and I am hoping it's not the dash switch. I sure if one can be purchased, it will be costly. Thanks for any info here as always.

More than likely you replaced the turn signal flasher. That is the one that is easy to find. The hazard flasher is a lot harder to locate. It’s usually up & behind the ashtray. There is no relay for the flashers. ‘67 & ‘68 dashes are similar.

Sometimes the switches get dirty from sitting unused. You can try working the switch back and forth to see if it will eventually turn on if the flasher is good.
 
Thanks mrfury68. I'll get under the dash (not as easy for me as it once was) and add or replace the other flasher. If need be I'll pull out the ashtray for easier access

Good point. I'll try that. The switch does seem a little tight.
 
On my '68 300 my 4-way flashers weren't working, but after cycling the switch about a dozen times they started working.
 
I just fixed my 4-ways on my '67 SF before I put it away for the winter. It's not the one behind the ash tray, that's for the turn signals. The 4-way was taped to the wiring harness beside the fuse box under the dash to the left of the steering column. It has it's own separate freestanding fuse nearby, in my case that was the problem, it had a shaky connection. Surprisingly the 4-way & turn flashers are the same. I found an old USA-made NORS flasher on ebay for cheap but didn't need it.
 
Thank you all for the helpful tips. I will be picking up a new flasher very soon. I remember for my turn signal flasher, I bought one that didn't last very long so I found another type that was clear rather the metal one I had before. The clear flasher has held up well and I believe I got it from O'Reilly's so I'll try to get another one like that for the hazard lights.

Looks like your question may have been answered already, but I might have some information from my stepdad that can maybe help you too. Take it from my stepdad whose owned multiple ‘67 Fury’s through the past 35 years, he says there is no relay and that its the switch. He takes his out, takes it apart, gets all the green corrosion gunk out with cleaner, cleans all the contacts, and puts a little white grease on it with a brush then that normally fixes it. He says he may have a switch he can sell you if you would need one, or if you don’t want to or are nervous to take it apart and do it just to come on down to our house and he can show you how to do it. Hope this helps you out.
 
Thank you SportFury70 for your input here and offer. I actually found another switch buried in my stash and hopefully I can get at least this one or the original switch in the car to work. These switches don't get used that often and due to their age, they are probably in need of cleaning. My gas and temp gauge aren't working due to a failed voltage limiter so when I remove the cluster to replace that, it will give me a better chance to remove the switch.

The dash switch can be bench tested easily with a multimeter. I’m sure they can become corroded over the years, especially in damp climates. The flashers do fail over time, they were basically just a bimetallic switch. New replacements are likely electronic. There is no relay, the flasher operates the lights directly. The D31-18-BK wire should be hot all the time, when turned on the switch distributes power to the lights. You could test the flasher by plugging into a known good one, it’s the same as the turn signal flasher. If I’m remembering right, the emergency flasher is actually nearer the bulkhead wiring in the thick taped wire bundle with the fuse close nearby. It will be hard to get to if you’re agility challenged.

Agility challenged, I am afraid I fall into that category but I can get under the dashboard; it just takes a bit longer. Your diagram illustrates a good starting point in identifying the hot wire feeding the flasher. Power there will prove that the system is okay to that point. Thank you.

I was able to locate my flasher connector but there was no flasher in it. As I said earlier it has been ages since I used them and I now think I may have robbed that flasher for the signal lights- a little brain freeze going here I guess.
I tested the connector and I have battery voltage there with the switch on. I may have another flasher kicking around but if not, I'll pick one up. If no go with a new flasher, I'll try turning the switch on and off repeatedly as mentioned. If need be, I will take the switch apart and clean it as suggested by SportFury70. Great tips from all here, thanks.

The federal government did not make the installation of hazard lights, side marker lights, seat belts and head rests mandatory until January of 1968. Therefore, your car being a 1967 is not required to have hazard lights.

Hazard lights were federally mandatory in 1967 with Chrysler dealer installations 1965 or possibly earlier. I believe some states may have made in mandatory in 1965 or 66. Head rests Jan 1969.
 
The National Traffic and Motor Vehicle Act 15 (U.S.C.A. 1381) with 19 federal safety regulations was signed into law by Lyndon Johnson in September 1966. It did not go into effect until January 1, 1968.

Do you have a link to that document and what section that information is in?

Even if the requirement was 1968, which I'm not convinced of, it's a moot point as the '67 Fury had hazard lights.

Here's pictures from the 1967 Fury dealership data book showing a 1967 Fury dash. I circled the "roadside warning flashers".

I don't have a direct link. I found it on the Library of Congress site. I understand that you have hazard lights in your car. My point is, because you are not required to have them they don't have to work.

Since the guy the actually has the '67 Fury in question lives in Massachusetts and posted this thread, here's the Mass. state regs for inspection. Look at 4.04 (10) and you'll see 1967 and newer.

However, you happened to mention my car (Although, I don't have a '67 Fury) and I said "why not see what NYS has to say". Here's the NYS inspection laws.

Top of page 44. 1966 and newer vehicles require hazard lights.
https://dmv.ny.gov/forms/cr79.pdf

IIRC, New York State was one of the states requiring hazard lights in 1966.

I did find National Traffic and Motor Vehicle Act 15 (U.S.C.A. 1381) and really, it's mostly legalize for the bureaucrats and doesn't specifically call out any of those requirements. At least that's the copy I saw, although I may be looking at the wrong section.
