All blinkers out

Hi guys, All my blinkers have gone out all at once. In the past when I have had speedy blinkers you know you have a bulb out. And the remaining blinkers work. This is something new. I have speedy indicators on my dash bot no blinkers work. Thank you in advance

 

Check bulbs and fuse. I’ve seen the dual filament bulbs blow and short causing fuse to blow

 

Bad flasher unit

 

Is your truck factory? Have you installed any aftermarket bulbs, load resistors, etc.
Further information will help us

 

Hope not, those suckers are built in to the Gen3’s!

 

Change the blinker fluid: https://www.youtube.com/watch?v=E6GsXhBb10k

Sorry- couldn't resist.

 

Oh no, that would be annoying. Hopefully just a fuse.

 

My truck is factory except I replaced a taillight assembly that came with bulbs, I guess I’ll start there. my frustration is usually they don’t all go out at the same time.
thanks ppl for all the input

 

Start with the tail light bulbs

 

Thank you everyone!!

 

Common area would be in stalk maybe. Do they work with emergency button switch ?

 

Hi
No emergency flashers either, but why the ore on I do not get the speedy indicators

 

If you live in CA, you don’t use blinkers anyway. Take out the bulbs, save some weight, get better mpg’s.

 

Same here in ct I’d swear newer cars don’t come with them sometimes

 

hell yeah, weight reduction

 

That's low man, real low.

 

Hi
Guys, update on my blinkers. It is not the bulbs. Bulbs work but do not flash. Interesting note. When truck is off the dashboard indicators flash normal speed but when started they flash fast

 

If a bulb is bad, it can cause that. Start replacing them and I bet you will find one that fixes it.

 

Thank you
I start replacing

 

Hi guys, I went looking for the master relay, could not find. Took to dealer. Turns out the master relay is in an electrical cluster to the tune of about $700.
thank for all the input
