Need Help. Blinkers trouble.
 

So needless to say my flasher are having issues. When I got the truck they didn’t work at all. I read some forums with similar issues and found that the connectors in the steering Column were loose when you raised and lowered the steering wheel. I also changed the flasher relay under the dash . So I fixed them and plugged them back in to the connectors and glued them in to where they won’t come out. Now I have blinkers but only the front. We can not figure why the rear don’t work. Also the hazard flashers do not work at all. Please help. .

I recently (last year) had an issue with my right rear brake/turn light not working. After tracing the wires and determining that I wasn't getting a signal to the back of the truck I turned it over to my mechanic. Ended up being in the turn signal switch. He replaced it and everything works like new again.

Edit: This was on my 2002 F150.

What year truck?
