More then likely it needs to be replaced, if its the actual signal inside the car, turn it on check outside the car which one it is and replace!!
your rear bulb is blown - replace the bulb The turn signal blinks fast because the bulb is going out. That is also why the others dont blink.
turn signal relay is bad
Buy a "highway" turn signal flasher
This happened to me. When my turn signal lights went out or would stay solid where I would have to manually make them blink it eventually made my break lights go out, but they would come on when I held the turn signal switch for high beams. To repair the issue you will need to get the whole turn signal switch fixed which is behind the horn and the airbag. Nice penny and it takes about 2-2 1/2 hours to repair it because there are wires behind your steering wheel that go to different things.
Why would you want the blinker faster. They should blink at factory specs.
Check your bulbs and your flasher.
If the check engine light does not flash when in the diag mode, the problem is the computer. Could be as simple as a failed lamp driver but a failed computer is toast and will need to be replaced/
I would highly suspect that there is a bulb out. Remove the Eight million hand tightened screws and the trunk lense will come out to access the socket. But check to see which one is out first.
Maybe a short somewhere...did you replace the flasher unit? No - it was blinking spuradically(?) - now I have to blink it manually and it won't blink at all with lights on.
turn signal relay fuse
You either have a bulb burnt out or the turn signal flasher is bad.
Probably needs a fuse.
you need to change the flasher can for the signal lights
That's usually an indication of a burned out bulb.
If a turn signal does not blink on a 1996 Honda Accord that it is time for it to be changed. To change the bulb and locate the light housing and remove the older light. Replace the light.
burnt fuse. check the fuse box
This may very well be a problem with your ground connections at that turn signal.
It means the bulb is out or something else is wrong.
Loose battery or alterator connections
That usually indicates that one or more of the bulbs have burned out. Turn on the left signal, get out of the vehicle and see which bulb is NOT turning on. Replace that bulb and the signal should work again. Also the flasher may not be working for one side.
Answer 1: You may need to replace the bulb. Answer 2: In my experience it indicates that one (front or rear) of the right turn signal bulbs has blown and needs replaced. If it blinks normal speed with the left turn signal then it's not likely to be the flasher relay. Hope this helps.
