New issue here turn signals just went out.  Flashers work fine.  No trailer hooked up or anything.  For as bit the turn signals would come on for about 2 clicks then go out both left and right.  Now I get nothing.  I looked under the hood and on the side panel for a signal relay but did not see one.  Anyone have any advice where to go from here?

Could the flasher relay in the in cab fuse box or the multi function switch on the column. The flasher relay controls both the flashers and the turn signals. At least it does in my 02. I just replaced my MFS because mine were acting strangely.

Thanks @dripley just knocked on their relay with my knuckle and it started working.  Will swing by and grab another relay on my way back from lunch.  

Good to hear.

I like the electronic flashers. Makes it nice for trailers and when switching to leds on the truck.
