Broken Hazards on 89 Ford Ranger

replace the hazard switch

you may have a bad flasher, hazards usually have a separate one

Have you replaced the relay because there's one of them as well with the flasher unit. I've been having a problem with my hazards not working but turn signals work fine. Maybe the arm on your steering column might be on its way out because they do get used alot.

Either the wiring has worn out or broken or the fuse has been damaged, you need to check out both.

Lets start at the beginning.
The turn signals and brake lights use different fuses but both go thru the turn signal switch and use the same bulbs.
Have you checked the fuses for each circuit and does each switch have power in and out ?

SOUNDS TO ME LIKE WHATS CALLED BY FORD AS THE MUTIFUNCTION SWITCH THAT HAS GONE BAD. IT WILL NOT SHOW ON ANY SCAN TOOL, SO FORGET THAT ACTION, I HAVE SEEN THIS OCCUR WITH MANY FORDS OVER MY 30+ YEARS OF WORKING ON JUST FORD PRODUCTS!!!

try pushing, pulling, tugging on hazard switch button when turn signal is on, left or right, if they start blinking, the turn signal switch is bad.

Check grounding at start of the wires coming from under the truck you will proble find a corried ground wire whitch cause afeed back to other lights thus completing circuit.

Can you just check to make sure the ignition key switch is not staying over to far and not backing off when you try to start it. I had a truck that did that and it messed up my turn signals until I brought the key switch back a little after starting it. Just a simple idea. Be kind with your rating for me. Raz

It Could Be The Flasher Switch Or Turn Signal Switch Now This May Not Be Whats Wrong with Yours Now My Ignition Switch came Apart on my car and i lost turn signals and E flashers i hope one of these will help
