87 f150 lariat, 5.0 4x4 dual gas tank. My son and I bought this as a project truck for him to drive. Fixed a handful of issues to make it road worthy but I cannot figure out the blinkier issue.
No blinkers or hazards. Taillights work - replaced all bulbs - checked all fuses under the drivers side panel - also replaced both hazard relays (the one on the top of the fuse panel and the one on the bottom of the fuse panel. I am at a loss now. Any suggestions would be greatly appreciated.

One other member suggested the actual blinker switch itself. Is there a way to test that?

 

do the brake lamps work? do the indicators light up on the dash ?

 

Brake Lamps work. The flashers and blinkers do not light up on the dash.

 

Did you try the multi function switch yet?

 

Is that the switch in the steering column? The main switch? If so i have not.

 

Yeah, that one.

 

Sorry to be the bearer of bad news but I think you are looking at going into the Column,
had to change the Master Turn Signal switch in my 91 TWICE - in 2 years.
Not the switches fault - Relative borrowed the truck and somehow broke the turn signal handle off.....
- It might be worth checking the wiring / connector on the column the see if you see something there, before tearing it apart....

 

Sounds like it's becoming unplugged to me if neither work

 

I don't think they had those on 87's. Mine doesn't.

 

If it is a conventional turn signal switch it will need to be replaced is my bet
