So I have an issue with my turn signals blinking fast.

Both left and right blinks fast, but normal with the hazards, Checked and cleaned all the sockets, all lights are working as they should.

Im lost on what to check.... need advice.....

 

Did you just upgrade to LED lighting if so you need to add a resistor to the rear turn signal lights, if you did not upgrade to LED check that all of your bulbs are working it can also happen when exterior turn signal lights are out.

 

no LEDs, all lights are working. 4 lights on each side.

 

Fender indicators are good?

 

yeah, every light thats supposed to be flashing is.

 

Aftermarket bumper(s)?

 

Might be a defective flasher (old school)

 

Where is it located?

 

Z128 is the flasher if you have a D1.

 

alright, I thought that was just the relay for it, I need to find a replacement and try it and see if it fixs the issue.
