My blinker lights are flashing rapidly front and back. I looked at fuse panel for possible flasher relay and only looks to be one relay present, but don’t think or know if that’s it.

Hi,

Does this happen on both sides or is it only one side? Also, check all the bulbs related to the signals. If one is out, this will happen. Keep in mind, most times there is more than one in the front and rear.

Also, I believe the turn signals are controlled by a module. There is a flasher for the hazard lamps. I attached a pic below showing both. See if you can locate them.

However, I still feel there is a bulb not working at some point.

Let me know.

Joe

Hello,

Thanks for responding back. All lights front and back are blinking fast. If I turn signal light on drivers side the front and back blink fast, same for passenger side. Is the illustration beneath dashboard or underneath hood? Thanks

Hi,

If this happened all at once and you are sure it isn't bulbs, I suspect it could be related to the module.

As far as the pic, that is under the dash on the driver's side.

Let me know what you find.

Joe
