I have located the hazard flasher under the dash behind the brake pedal on the firewall and was wondering if the flasher right next to it is the turn signal flasher because while I was driving I turned on my turn signal and it made a strange buzz noise under my dash and then I had no signal lights and was wondering if this might have burnt out.

I have changed the Flasher, switch and fuse for my turn signal. The Hazzard lights function properly, but when I try to check my turn signal, I get nothing. Not even the associated clicking. What is my next step?

Hi
The switch you replaced was that the turn signal switch assembly?

Yes, I removed the old and replaced with a new one. The wipers and cruise control both also work so I'm not thinking I have a switch issue.

Next step then is get a wiring diagram a volt/ohm meter. And start testing all the wiring.
