My turn signals and hazard lights stopped working. All four

This answer was rated:

My turn signals and hazard lights stopped working. All four turnal signals front and back don't work, so can't be bulbs. I checked all the fuses and couldn't find any that were blown. Is there a flasher that controls both that could have blown out? Where would it be located?

-Could you explain your situation a little more?
-What year & model is your Buick ?

I have a 2003 Buick Century. While driving the turn signals stopped working. I also tried the hazard lights and nothing. I checked all the fuses, both in the dash and under the hood to see if any related to turn signals or hazard lights were blown. All looked good. All the other lights work, brake lights, back-up lights, head lights, etc. I'm assuming it can't be bulbs since all four lights wouldn't go out at once. Could it be some kind of flasher relay?

Ok, yes I would first check the signal flasher relay.They usually kinda hide them ,I am sending info to help.I would check for voltage at this plug & replace the flasher.
