if its like the late 90's Monte Carlo's . The turn signals get their power through the hazard switch. It will most likely need replace.
Early to mid '00's Monte Carlo's and Impalas have hazard switches that are fairly prone to failure, some reports as high as 60% OE failure ratings. The turn signals are routed through the hazard switch, and when it goes, they both go. Aftermarket replacements can be found on eBay for under $30.
Gm needs to build better units, Have you noticed how many turn signal problem posts there are online?
Isn't your car under warrenty? Check for recalls.AnswerNothing needs to be replaced. The problem isn't exclusive to GM; it is all vehicles with a flasher switch mounted on top of the steering column. Over time, dust builds inside the switch and pretty soon, the ground gets gummed up. Spray WD40 or better yet NAPA's "Brake and Electric Motor Cleaner" down the flasher switch hole; work the switch up and down several times and everything will work fine again. If the flashers regain power but the turn-signals do not, spray some cleaner in the directional switch hole as well. It works like a charm!!!
Actually the wiring is frayed a bit so if you wiggle it up and down or do what mechanics refer to as the "Beezer Boy Shake", you should be in business.
My research to date finds that the turn signals and hazard signals are controlled by a common relay. That relay is behind the hazard relay switch. My 2002 Audi A6 has the same symptoms you describe, and I will be removing the hazard switch to get at the relay for replacement. Good luck.
Flasher is faulty.
If the turn signals are inoperative check the hazard switch, if the hazards don't work replace the hazard switch, the signals will start working. if the hazards are ok ,the turn signal switch may be bad.
Often, a separate flasher unit is used to activate the hazard flashers. This unit might be bad, or the switch to activate the hazard flashers might be bad. answer always there are 2 flashers.one for turn signals other for hazard replace hazard flasher They have separate fuses also.
turn signals won't work. changed all the bulbs. Hazard lights work. 1999 Chrysler Sebring hardtop
The flasher is a type of switch that regulates the turning on and off of your vehicle's turn signals and hazard signals.
There are 2 flasher units under the dash. 1 for the turn signals and 1 for the hazard lights. They are round and you need to pull them straight out, then replace them. What I do is I figure out which one works the signals and I replace that one with a heavy duty one, the other can be a regular one. If the lights don't come on but the signals are working it can sometimes be the bulbs, other times it's a short like the other person said.
Check the fuse
hazards and turn signals have separate flashers. replace flasher for turn signals
== Hazard and turn signals switch are different. Sounds like you need a new turn sig. switch. The turn signals are routed through the hazard switch. Re-check fuses 4 and 19. If they are fine, check/test the hazard switch and related wiring; if the switch is faulty, replace it. If the switch is good, check/test relay in position 12.
Separate circuits, separate fuses, separate flasher relay. Check the hazard fuse, hazard flasher and hazard switch.
Bio-Hazard Battle happened in 1992.
Make sure hazard switch is pulled all the way out May be a problem in thw steering column
try replacing all sets of fuses for the hazard and the tail lights.
Turn signal flasher?
If your 1999 Ford Expedition has turn signals that do not work but hazard lights that do work, it is likely that you have a fuse that is blown. You might also have a wiring issue including exposed wiring.
There are two flashers, one for the hazards and one for the signals.
Hazard and turn signals usually use separate flashers, switch the flashers to see if turn signals work and hazards don't, if so replace the flasher you need to replace the blinker flasher unit it is different from the hazard unit they cost about 4 bucks the flasher unit is the big round thing in the fuse panel in the dashboard
If your hazard lights don't work but your turn signals do work it could be that your Hazard Lamp Flasher needs to be replaced. Your car has both a "hazard lamp flasher" and a "turn signal lamp flasher". Your "turn signal lamp flasher" is working but your "Hazard Lamp Flasher" may not be working. Buy a new "hazard lamp flasher" and install it. The hazard lamp flasher is located behind the instrument panel to the left of the steering column.
It is most likely the Hazard Switch. The turn signal and the hazard flasher are the same unit and will affect the operation of both. If the turn signals work, then it is more likely to be the hazard switch which is about $30 part.
When both of the turn signals (indicators) of a car blink simultaneously, it is usually because the hazard lights are turned on.
Bad switch? Bad hazard flasher?
The common reason why is a fuse blew.
Integrated with the hazard flasher switch (which is in the dash)
