All of my signal and hazard lights quit working all at once. one day they were working and the next day they didn't. There was nothing changed or worked on in between those times or for sometime before. All the running and brake lights work fine.

I've checked all the fuses and also changed the flasher with no change.

 

Time to break out the Meter and do some testing.

See if the fuse has voltage on both sides



Bad new flasher did you test the old one ??

 

I pulled the switch out today and cleaned it really good. Then I packed it with dielectric grease and now it works great.
