Turn signal indicator blinks rapidly

[royp4]

Hi,

Tonight I noticed that the left turn signal indicator is blinking rapidly when I switch left turn signal on. This is happening on my 03 996 cab. Does anyone know what this rapid blinking indicates? Thank you in advance.

Sometimes if both front and rear lights/bulbs are not both good they can do that.  A poor ground is another reason...  That's my 2 cents.  Keep us posted...

Have you made sure you don't have any burned out bulbs to start?

I haven't checked anything yet. Just noticed it when I got home from work tonight. Thanks for your ideas. I was just throwing this out there for the Renntech braintrust.

Then I'm sure that someone from the "braintrust" will answer you.  However you might check all your lights to be sure they're all working so you begin to narrow down the problem.  You might even remove the light bulbs and be sure that the contacts are all clean.  You can buy electrical contact clean in an aerosol can at your favorite auto parts house.

 

I'm guessing it's a bad bulb, bad flasher, or bad ground, there's not much else that can go wrong.

It's more than likely to be one of your left turn bulbs or the connection to one of the bulbs.  Put the hazard flashers on and view the car from the outside to see which one is not working. 

 

If it's the side flasher it juts pulls out and it's easy.  If it's the back that also easy. Lift the engine cover and unscrew the nut that holds the light assembly in place.  Remove the light unit and locate the flasher bulb.  It will be a 21w single filament bulb. 

 

The front one is a bit more tricky as you will have to remove the whole headlight unit.  It's easy to do as it slides out, but a bit more difficult to put back.  You might need help if you have not seen it done before.

Thank you all for your input. You guys rock!  I hope that one day I may be able to help one of you in some way.

It was a burned out bulb which I was able to replace in about 10 minutes. Thank you all for your willingness to help.

Figured it likely was but I'm glad it was that easy for you.  Thanks for reporting back the solution and closing out your thread.
