12 reasons car turn signals don't work or flash crazy fast
HTML-код
- Опубликовано: 28 сен 2024
- If your turn signals are not coming on or flashing too quickly on your car, there are several potential reasons for this issue. Here's a comprehensive list of possible causes:
number one
Burned-Out Bulbs: A common reason for turn signals not working is one or more burned-out bulbs. Check all turn signal bulbs (front and rear) to ensure they are in good working condition.
Dimmer or Non-Compatible Bulbs: Using bulbs that are not the correct wattage or type for your vehicle can cause issues. Ensure you are using the correct bulbs recommended for your car.
Make sure the new bulbs are working. Use the voltmeter to test.
#2
Blown Fuse: A blown fuse in the turn signal circuit can prevent the signals from functioning. Check the fuse related to the turn signals and replace it if necessary.
#3
Faulty Flasher Relay: The flasher relay regulates the flash rate of the turn signals. A faulty flasher relay can cause issues like rapid flashing or no flashing at all. Replace the flasher relay if it's malfunctioning.
#4
Corroded or Loose Wiring Connections: Corroded or loose wiring connections in the turn signal circuit can disrupt the electrical flow.
Inspect the wiring and connections for damage or corrosion, and repair or clean them as needed.
#5
Bad Turn Signal Switch: The turn signal switch on the steering column can fail over time, leading to issues with the signals not working correctly.
If other components are in good condition, consider checking or replacing the turn signal switch.
Number six
Faulty Hazard Warning Switch: In some vehicles, the turn signals are integrated with the hazard warning switch. A malfunctioning hazard warning switch can affect the turn signals.
Faulty Multi-Function Switch: Some cars have a multi-function switch that combines the functions of turn signals, headlights, and more. If this switch is defective, it can impact the operation of the turn signals.
#7
grounding Issues: Poor grounding in the turn signal circuit can result in erratic behavior. Check the ground connections for corrosion or looseness.
#8
Battery or Charging System Problems: Low battery voltage or alternator issues can affect the electrical system, including the turn signals.
Make sure your battery is in good condition, and check the charging system if necessary.
#9
Electronic Control Module (ECM) Issues: In modern vehicles, the ECM can influence turn signal operation. If you've ruled out other causes, consider having the ECM checked for faults.
Software or Control Module Updates: In some newer vehicles, software updates or control module reprogramming may be necessary to address turn signal issues.
Number 10
Environmental Factors: Extreme cold or moisture can affect electrical connections and cause intermittent issues with turn signals.
Number 11
Aftermarket Modifications: If your vehicle has aftermarket electrical modifications or accessories, they may interfere with the turn signal system.
Recent electrical work on your car brake lights towing hitch et cetera
Number 12
Wiring Harness Damage: Damage to the wiring harness, such as from accidents or rodents, can disrupt the electrical flow.

When I was young, hand signals were still in use. All you needed was a little Absorbine Junior liniment and a couple of aspirins and you were good to go.
Using hand signals sucked when it was raining outside though.
I can't remember the last time I saw someone using hand signals. I think it was me.

“Hey… What’s that old geezer pointing at ?
CRUNCH!!!
I wonder what the road rules were for horses and carriage?
“I’m a goin that a way.”
“Well ,Im a goin this a way”
“Nice talkin’ to ya’”.
“Yup”.
I'm at about the same situation as yourself, going to mechanic next. But I really like your suggestion of double checking all bulbs and visible wiring. I'll do that first. Thanks for the suggestions.
Thanks Mr Bill.😀
Once, I replaced all the old brittle wiring in my trailer. Did a nice neat job with wire insulation and zip ties. Well, none of the lights would work. I assumed it was lights or sockets. I replaced all the bulbs, cleaned the sockets and put dielectric grease on them. Still no lights. After half a day of scratching my head, I found it was the brand new wiring that had a break in it somewhere. I was pissed because of all the work I put into properly installing it. Ran some new wires that I put together myself and then I had lights. So the moral of the story is,, even brand new stuff might not work.
Hey Brad, same here. I once replaced a fuse with a fuse that wasn't working. It caused a lot of problems.
When indicate left relay clicks and indicators work but when indicate right relay doesnt click so think it between switch and relay new relay new switch checked relay fuses bulbs lights etc but hazards work all round
your issue could be related to a wiring problem or a faulty connection, specifically in the circuit that controls the right turn signal. Since the left indicator and the hazard lights are working, this suggests that the relay, bulbs, and fuses are likely in good condition. Here are some steps they can take to troubleshoot the issue:
1. Check the Turn Signal Switch Wiring:
Since the customer has already replaced the switch, they should inspect the wiring harness connected to the turn signal switch. Look for any loose, corroded, or damaged wires that might be interrupting the signal to the relay when indicating right.
2. Inspect the Relay Socket:
Even though the relay has been replaced, the issue could lie in the relay socket itself. Check for any signs of corrosion, bent pins, or loose connections in the relay socket that might prevent the relay from engaging when the right signal is activated.
3. Test the Right-Side Wiring:
Trace the wiring from the switch to the relay and then to the right-side indicators. There might be a break or short in the wiring specifically affecting the right turn signal. Using a multimeter, they can check for continuity along this path.
4. Check Ground Connections:
Ensure that the ground connections for the right-side indicators are secure and free of corrosion. A poor ground connection can prevent the indicator lights from working correctly.
5. Inspect the Hazard Switch:
Since the hazard lights work on both sides, the issue might also be related to the hazard switch, which could be affecting the right-side turn signal when the turn signal is used independently. Check the wiring and connections related to the hazard switch as well.
@@RobbsHomemadeLife thank you
I turn my head lights on, right turn signal wont work. Head lights off trun signal works fine. Jeep compass 2010.
This issue with the turn signal on the Jeep Compass 2010 is likely related to an electrical problem, most commonly a grounding issue. Here are a few steps your neighbor can take to troubleshoot and potentially resolve the problem:
1. Check for Grounding Issues
The most common cause is a poor ground connection. When the headlights are turned on, they may be drawing current through the same ground as the turn signals, which can cause them to malfunction. Check the ground wire connections near the headlights and turn signal assemblies.
Clean and tighten any loose ground connections. Rust or corrosion can cause bad grounding, leading to electrical interference between the lights.
2. Inspect the Bulbs
Ensure the correct type of bulbs are installed. Sometimes, using incorrect wattage bulbs can cause cross-connection problems.
Check both the headlight and turn signal bulbs for any signs of damage or improper installation. Replace any faulty bulbs.
3. Check the Turn Signal Socket
Inspect the turn signal socket for corrosion, moisture, or wear. If the socket is damaged or corroded, it may need to be replaced.
4. Examine the Wiring Harness
Check for frayed or damaged wiring, especially around the headlight and turn signal circuits. Look for any exposed wires that could be shorting out when the headlights are turned on.
5. Test the Turn Signal Relay or Flasher
The turn signal relay could be faulty. Replacing this is usually inexpensive and straightforward. It's worth trying if the above checks don't reveal anything.
6. Look for Aftermarket Modifications
If the vehicle has any aftermarket lighting or electrical work, this could be affecting the turn signal and headlight circuits. Consider inspecting or removing aftermarket equipment to see if it resolves the issue.
Just got my signals fixed. I was installing a dashcam with fuse bridges, I put the HAZARD fuse in the wrong place, $214CDN later, the signals work! Oh silly me!
Hey John I know exactly how you feel I'm so happy the video helped you thanks for letting me know
Never buy a tweeker car at the auction.
For some reasons they have more wires than a telephone switch station.
What is a tweaker car?
@@RobbsHomemadeLife Meth addicts nickname is tweakers. Their cars have wires going everywhere and wires that don't belong and stuff wired up by running extra wires from stripping wires of appliances.🙃😊
Why are you telling us your personal stories? lol
Well that's what happens when you don't press the artificial intelligence button
I am a HUGE fan of using dielectric grease in sockets and plugs when replacing electrical components. It repells moisture, prevents corrosion and just makes removal in the future much easier.
Love the video. Good information
Berry thank you so much I appreciate that
Hi Robb! Good information to know. I can pretty much take care of the basics on my car, bulbs, oil change, brakes and things that are basic repair. I hope you have a blessed night!
That's great willows. You're doing better than a lot of people that's for sure. You have a good night too.
Good information. I have had over forty vehicles , so lots of experience with electrical gremlins 😮. Now days, it’s off to the professionals 😊👋🐿. PS. My first vehicle was a 58 VW van😂 learned so much 😊👋🐿
Hey Oscar I think that's so cool you had a 58 VW van. They were so simple to work on but I seem to have spent a lot of time working on them
I have a 2008 Pontiac G6.
I have owned it about 8 years.
The drivers side headlight has blown about 7 times.
Never replaced the passenger side yet.
Most of the time its the a$$ behind the wheel not turning them on. Lol
The front signal lens enclosure thing (?) filled with rain water and corroded the lamp and socket. Had to replace the socket/lamp and find, fix the leak on the lens.
Hey thanks for taking the time to let me know much appreciated
You missed Number/# 13. Gremlins. Dad always reminded me to check the simplest and most obvious thing first, so good you started with the bulb. Posters need thick black felt pen for us old folks who are visual learners (or is that visually impaired?) or are they only large prompt cards for yourself?
Hey island gal, those posters did not come out very good did they. I was in kind of a hurry. They ended up just being visual reminders for me. I had intended on having a lot of other video to be placed over my dialogue so they wouldn't have been as important but that didn't turn out either. Hopefully the video helps somebody.
Blinker Fluid!!!
I hope I never live long enough to have to drive a new car.
I'm debating what to do with my car. I'm probably going to keep it but if I had to get another one I think I would still get it used Corolla or Camry.
I have a 94 suburban. It has modules, an ecm and you can plug an obd1 scan tool in. I just have a code reader that makes the check engine light flash to tell me what it thinks is wrong. Last time it was accurate. Bad throttle position sensor.
Thanks!!
2:13 - In the early 90's I rented a beater rental car on the Bahamian island of Andros that would honk the horn in unison with the flashing turn signal lights. Interesting how many unrelated components can be intertwined in an automotive electrical system.
John that's pretty funny. On my van I had repaired my brakes poorly and they sounded like Michael Jackson when I applied them and I also installed a new headlight wrong so it was aimed high and would hit people in the rearview mirror so I would come up behind people at night time in Miami and step on my brakes and blow the horn and have my lights in their rearview mirror while my brakes were making a really loud Michael Jackson noise
@@RobbsHomemadeLife 🤣
🤣😂🤣and you didn’t even get shot?!?
No but I learned a lot of foreign curse words
@@RobbsHomemadeLife 😂😂😂😅🤣🤣😭😂😅
I have this issue on one of my motorbikes.
Bulb is good, checked with multimeter. I'm getting current to the housing, but when you plug the bulb in it's just not working. Next step is to take the connector and wire off the side that is working and start working backwards with a known good loom to find where the issue is.
Just happened. Quick flash.
Somewhere theres a disconnect in the highbeam wire. Couldnt find it so ran a wire from the other one till i find it in the wire harness. ( it was cold so i just ran the wire for a minute. )
Hello candy thanks for watching good luck with your electrical problem.
did you end up fixing it? we are having this problem where it'll flash for a second and then kick off.
I left the flashers on 😅t drained the battery. Got a jump.Now they are not working turn signals and hazzards
hey tay, If your car's flashers, turn signals, and hazards are not working after a battery drain and jump-start, it could be due to several issues. Here are some steps to diagnose and potentially fix the problem:
Check the Fuses:
Locate your car’s fuse box, which is usually under the dashboard or in the engine compartment.
Find the fuses related to the turn signals and hazard lights. This information can typically be found in your car’s owner manual or on the fuse box cover.
Inspect the fuses for any signs of damage or a blown fuse. Replace any blown fuses with new ones of the same amperage.
Inspect the Relays:
Your car might have relays for the turn signals and hazard lights. These relays could have been damaged during the jump start.
Check your owner’s manual for the location of these relays and test them if possible. You might need a multimeter to test the relays or simply swap them with a similar relay in the fuse box to see if the problem is resolved.
Check the Turn Signal and Hazard Flasher Unit:
Some cars have a separate flasher unit that controls the blinking of turn signals and hazard lights.
This unit might be faulty, especially after a power drain. Locate the flasher unit (often near the fuse box) and consider replacing it.
Examine the Battery Connections:
Ensure the battery terminals are clean and tightly connected. Loose or corroded connections can cause electrical issues.
Sometimes, a weak or drained battery, even after a jump start, might not provide adequate power for all electrical components. Make sure the battery is fully charged or consider getting it tested and possibly replaced.
Check the Wiring and Ground Connections:
Inspect the wiring related to the turn signals and hazard lights for any visible damage.
Ensure that all ground connections are secure and free of corrosion.
Test the Turn Signal and Hazard Light Switches:
The switches themselves could have been damaged or malfunctioning. This might require a more detailed inspection or testing by a professional.
Reset the Car’s Electrical System:
Sometimes, simply disconnecting the battery for a few minutes and then reconnecting it can reset the car's electrical system and resolve some issues.
hope it helps
I put on new videos every week for the last 17 years.
2013 Hyundai Elantra - front passenger turn signal works fine when headlights are off. When headlights are on, turn signal lights…but doesn’t blink. Any ideas? Thanks!
It sounds like you might have a grounding issue or a problem with the electrical connection in the circuit that controls the turn signal when the headlights are on. Here are a few things you can check:
Check the Bulb: Make sure the turn signal bulb on the front passenger side is not burnt out. Even if it lights up, it might not be making a proper connection to blink when the headlights are on.
Inspect the Socket: Examine the socket where the bulb sits. Sometimes corrosion or a loose connection in the socket can cause intermittent operation. Clean the socket contacts and ensure they make good contact with the bulb.
Check the Ground: Poor grounding can cause issues with electrical circuits. Check the ground connection for the turn signal on the front passenger side. Make sure it's clean, tight, and securely connected to the vehicle's chassis.
Wiring Inspection: Inspect the wiring harness that connects to the turn signal bulb. Look for any signs of damage or corrosion along the wiring. A damaged wire can cause intermittent operation or failure of the turn signal.
Relay and Fuse: The turn signal circuit is controlled by a relay and is often fused. Check the relay and fuse associated with the turn signal circuit to ensure they are functioning correctly.
Multi-Function Switch: In some cases, the issue might be with the multi-function switch (the stalk on the steering column that controls the turn signals). If the switch is faulty, it might not send the proper signal to the turn signal circuit when the headlights are on.
If you're unable to diagnose or fix the issue yourself, it's best to consult with a professional
@@RobbsHomemadeLifethank you was having a similar issue
Just change the car 😄
Hey Oscar, I don't have car problems I have potential RUclips videos. But seriously What Car would you suggest I purchase? Inquiring minds want to know.😀
@@RobbsHomemadeLife hmmmm...my bucket list car is a red 1973 Chevy Nova with a 350 and standard transmission (4 on the floor) 😁
@@saltyshellbackthat would be insanely hard to fix on a car like that bc parts, I feel like the car he has will last YEARS, electric issues are nothing compared to a blown motor or trans, if I could give a opinion I’d suggest he’d keep this gem
Thank you for your video.
It's all about the blinker fluid.
Don't ask me how I know.
Keep up the great work.
Hey thanks a lot I really appreciate that. I'm trying.
Blinker fluid😂😂😂😂
😂,, lol I just said that to my inspection mechanic when we were talking about my quick flash cause high beam was out. Lmfao!
He was so glad I was joking. Cause imma girl. 😂
On a serious note, i can use the drivers vontrols for the passenger eindows, but passenger window buttons do mot work, same side the high eam diesnt work and we couldnt gind that either , ( i just vommented it was vold do we ran a wire from the good one.. after doing the immediate checks. )
