My hazard lights won't come on at all. The turn signals work fine, as long as the hazard button is not depressed. The hazards used to work, but if the hazard button was pressed and I put on a turn signal, both would stop working. Hazard button in = no turn signal or hazard. Hazard button out = turn signal works fine. I tried to eliminate the switch to see if that would help. If I disconnect the wire harness from the hazard switch, the turn signals will not work either. I also tried swapping relays to see if one was busted and they all work fine in other places.

This vintage era GM vehicle is known for turn signal issues due to bad hazard switches. Replace the hazard switch and everything should return to normal

YOU MIGHT HAVE A BURNT OUT RELAY IN FUSE COMPART UNDER YOU CARS HOOD CHECK THAT OUT THRU YOUR CARS MANUAL,IT WILL SHOW YOU WHICH RELAY IT IS?

if fuse okay,could have faulty multifunction switch.

renew the hazard warning light switch as this is faulty and thats why your indicators are not working

OK try this, push and hold brake then push on the hazard switch if brake lights come on then replace the turn signal switch.

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.

You likely have a sticking hazard signal relay or hazard switch. Try turning on the left or right turn signal then depressing and releasing the hazard switch a few times. If the lights begin working you probably have / had a sticking switch. They don't get used often and this is not uncommon. Also could be relay. Thats a cheap fix and easy to locate. Should be with fuse box or near it.

If this helps please rate my answers.

I had this same problem. I replaced the turn signal switch in the steering column and it worked great. To test for this, check your lights while wiggling your hazard light button and/or signal lever. When I pulled my hazard button forward, all my lights would come on.
