My turn signals are rapidly flashing, and I can't find the relay. I would prefer not to put load equalizers if possible. Can you help please?

Hi,

The flasher is integral to the hazard switch assembly. Take a look at the wiring schematic below. I highlighted the component.

Because of this, I don't feel you have a choice other than a load equalizer.

Take a look at the wiring schematic below and let me know if you have questions.

Take care,

Joe

Is there a complete hazard switch assembly available with a higher resistance that would solve the problem? I understand how hard it is to access the hazard switch, but I prefer that if possible.

Hi,

I'm not familiar with one being available. However, since people are changing the original bulbs with LEDs, there is a good chance it is.

Have you tried contacting a parts store? Don't laugh, but I have purchased bulbs from a site called HIDnation. Com They offer just about anything you can imagine at a good price. You may want to check them out and see what they suggest.

Also, I have nothing to do with the site. I'm only suggesting them because I've had good luck with them. I don't want you to think I'm getting a kickback. LOL

Let me know what you find.

Joe
