Turn Signals and Hazard Lights

Why would the hazard lights blink on all four lights but the turn signals do not flash?

funny you should ask... this just happend to me, two days ago [!] on my 1995 Chevy lumina.

i read the owner's manual, and found that the turn signals will not work, as long as the hazard lights are engaged. well, needless to say, not only had i *not* engaged the hazard lights, but as it turns out, i *couldn't* engage them!

there is a plastic sheath/button that fits over the actuating rod. it's the rod which really engages the hazard flasher switch, down, inside the steering column. this sheath/button is the piece that sticks out the top of the steering column, with the little, concentric, double-triangles on it. you're supposed to push it down to engage the hazard lights, and then push it again to disengage them.

when i tried to turn the hazards on, they wouldn't stay on; if i let the "button" go, they went back out; if i held it down, they would flash.

i lifted up on the sheath/button, and it came right out of the steering column. i put the sheath/button back in, pushed it down, and again the hazard lights would flash as long as i was holding it down, but it wouldn't *stay* down. upon closer examination, i saw that part of the bottom of this sheath/button was broken off.

my mechanic found that the broken piece was still down in the column, wedging the hazard actuator rod in and "almost-on" position, thereby disabling the turn signals. he pressed the actuating rod quickly, a few times, and finally the offending, broken bit popped out.

he told me that as long as i don't use the hazard lights, I'll be all set. because that acutator doesn't seat itself vertically, without the broken sheath, if i need the hazard lights and push the actuator rod [even without the sheath/button on it] i could knock the rod out of kilter, and my turn signals will be out of commission, again.

guess what? i can live without my hazard lights.

good luck,

p.s. or it could just be a fuse. ;)

^^^^ THANK YOU! THANK YOU! YOU FIXED MY PROBLEM AS WELL! My turn signals all of the sudden went on me today. the hazards still worked but the turn signal did not. I was worried because my dad had a probelm with his car in which his tailights would not come on when he switched his lights on, and it cost him a couple hundred to fix! His light switch was busted in the steering column. However i read this page pulled out the hazard light switch above the steering wheel and sure enough, THERE WAS A LITTLE BROKEN PIECE OF THE HAZARD LIGHT SWITCH STUCK INSIDE! I used needle-nose pliers to remove it and turn signals work FINE! Thanks Again R.J.

if you mean: "why do hazard lights flash when brakes are on", then the answer is because vehicles are equipped with a hazard light relay that supercedes the brake lights. This way, slow moving vehicles can operate under hazard lighting.

If the lights come on but do not flash, replace the flasher relay. If they will not come on check the fuses.

A flasher relay interrupts power to the hazard lights making them flash. The relay can be a dedicated relay or it can be the same relay that operates the turn signals. Depends on the make, model, and year of the vehicle.

Some vehicles has a flasher relay for the turn signals and another one for the hazard lights. Are you sure you replaced the correct one?

You can buy special bulbes that blink your lights slowly or you can computerize them.
