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.

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.

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.

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

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!

@RobbsHomemadeLife 3 ай бұрын

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

@RobbsHomemadeLife 2 ай бұрын

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.
