So I was pulling onto the highway and I signaled to hit the on ramp (signal worked for this), driving up the on ramp I meet the speed and goto merge into traffic goto turn on my signal to merge in and nothing, try the other signal and again nothing, try the hazard lights and nothing. No clicking, no hyper blinking no word at all, they just stopped working. All my lights work, head lights, reverse lights, brake lights, even the turn signals light up in DRL form but will not blink.

Flasher?

 

Considering I just had a problem in this area I'll throw out a few things that were wrong with mine.

Check your fuses if you haven't already.
Check your Turn signal flashers.

Thats about the only advice I have for you.
I had to take my truck into a shop for the fix since I don't know enough about electrical or had the time to do it.

 

SOmething else going on here, had the same problem and it was because some ( GRRRRRRRRRR) idiot had worked on the lights at the rear of the truck Question was it raining?
