I need to know where the flasher is that works the four ways. Mine are out. The turn signals work fine only the emergency flasher is out. I have found one flasher unit on the side of the dash by the driver’s door but where is the other one located and which one is which.

 

It should be right beside the one in the dash but, if it isn't I would check under the hood in the fuse box.

 

I only see one in the dash and did not see another in the box under the hood. There was a fuse marked flasher but it checked out OK.

 

It's the blue relay in my truck look in this picture.

 

Must be all together. Left turn , right turn and flash. that is the only one that i can find . thanks for the help i'll pick one up today.
