No hazard lights

1972 have signal lights but no 4-way flashers. Any ideas where to start how to fix?

A lot of times, the 4-way flashers have a separate flash unit. Looks similar to the normal turn signal one. Swap one for the other and see if the problem moves as well.

Well it’s not the flasher any other ideas?

Any time there is a failure of an electrical item, the first thing to check is the fuse(s).. In this case, the hazard flashers have their own fuse, separate from the turn signals. If the hazard fuse is good, suspect the turn signal switch.. If the fuse is blown, suspect a short in the circuit somewhere.

Turn signal or hazard switch?

The hazard switch is part of the turn signal switch, not serviceable..

If you look at the home page of the electrical forum and find the heading "electrical forum Faqs by Vettevet", then click on it and scroll down to the Heading ", Why won'?"t my turn signals work?" You will get the answer you need.

You need to find the middle wire in the harness plug which should be a brown wire. Then check it for 12 volts with the key off or on. If you don't get 12 volts then your hazards will not work and if you do then the problem is in the signal switch.
The second post will tell you how all the wires are run and what they do.

Ok no voltage on the brown wire so not the switch. ‘‘Twas the fuse.
