Honda Accord Flasher Relay

How to Solve Honda Accord Flasher Relay Problems

Flasher relays control the electricity flow to your signal lights by cutting it off intermittently, causing the signal lights to flash. Without this device, you would have malfunctioning turn signal lights and hazard lights, leaving you unable to send signals to other drivers. When such problems crop up, be sure to troubleshoot them as soon as possible so that the issue can be fixed immediately. Here are some problems with the Honda Accord flasher relay that you should know of:

Flasher relay clicks quickly even without being prompted but works when turn and hazard signals are switched on

One cause of this problem could be a malfunctioning hazard or turn signal switch. The electrical components inside these switches could have worn down, making the switches lose their resistance and allowing tiny amounts of electricity to flow through them. This flow of electricity could be what is causing the clicking noise. One easy test would be to remove the switches one by one to see if it will make the sound go away. If the clicking stops after removing a certain switch, then that switch is the one malfunctioning. Replace it immediately in this case. If the switches all check out and work perfectly, then inspect the relay next. The easiest way to do that is to remove the old relay and replace it with a new one. If that removes the clicking noise, then you've just solved your problem. If the clicking noise still refuses to go away, then check the wiring instead and look for anything that is damaged or broken. Replace this as necessary.

Left turn signal does not initiate but everything else works

If one of the flashing lights refuses to work, try checking out the bulb first, which in this case is the left turn signal light bulb. Open up the light assembly and inspect the bulb. If the filament looks burned out, replace the light bulb with a new one. If the bulb looks fine, test out the relay by replacing it with a new one as mentioned in the last problem. If the turn signal works after doing so, keep the new relay in and throw the old one away.

Testing the relay with an ohmmeter

Another way to test the relay is with an ohmmeter. This will accurately test the electricity flow through the unit. Just connect the probes to two different terminals before checking the readings on the meter. You should get a zero reading, which means that no electricity is flowing between the terminals.

  • How to Keep Your Honda Accord Flasher Relay Functioning 27 February 2013

    We don't think much about our signal lights. But without them, changing lanes will be a challenge since drivers behind us will be clueless to our intentions. Breaking down in the middle of the road will also be dangerous if you have no hazard lights to alert other people of your predicament. The flashing lights are made possible by the flasher relays, which turn the lights on and off. Keeping our signal lights working requires that the flasher relay be taken care of. Read on to learn more tips about the maintenance of the Honda Accord flasher relay.


    Maintain the wires of the signal lights.


    The life of the flasher relay hinges on the overall health of the electrical system. Inspect wire harness for damaged and broken wires and have them replaced right away. If you keep you running your car with faulty wires for too long, the irregular flow of electricity could damage the electronic components of the relay, making it malfunction. You don't really need to do this regularly; just be sure to check them out as soon as you sense that your signal lights are having trouble.


    Replace the flasher relay as needed.


    Flasher relays will eventually go bad. You'll know this as soon as your signal lights start acting weird or once they refuse to respond when you try to switch them on or off. You can also use ohmmeter to see if there is any continuity in the unit. Working relays have zero continuity so if the readings show otherwise, it's time to replace the relay.


    Test out the signal lights before leaving.


    If there is any problem with your flasher relay or with your signal lights, it's best to know of these problems before you go out driving on the road. This way, you can catch problems early on and fix them. Checking your signal lights is very simple. Just turn on your car's engine and switch on the left signal light. Get out of your vehicle and check if the left signal lights are working. Do the same with the right signal light and the hazard lights. If one of the lights do not seem to work, try to troubleshoot the problem to figure out the cause. The usually causes of signal light malfunction are bulbs, wires, fuses, and even flasher relays.
