i used a trailer and now my blinkers are on the fritz. they blink once or twice and stop. i have a 2004 supercrew f150 lariat.don't know where anything is, even the fuse box.any suggestions?

 

Check the glove box for the owners manual. I would turn the blinkers own and walk to the back of the truck and see if the are both working. If one is out check the bulb.

 

Are you talking about the Trailer signals or the trucks ?

If you do not have an owners manual, you can download one here :

probably one of the trailer lights is out

 

my trucks blinkers are not working, i checked the fuses and all of them are fine. i suppose i should just take it into ford. all the lights work, they blink once and shut down.

 

On the surface that sounds like a problem with the solid state flasher, but that does not really make sense to me.

When you use the Hazards, so they have the same symptoms ?

When you plugged in the trailer, did you use the factory 4 pin / 7 pin adapter ?

 

My trailor was doing some weird stuff with the blinker lights. Everyone one here told me to check the fuse, so what did I do? I rewired my trailor. Got it rewired and had the same problem. Changed the fuse and it worked fine. You might want to start off with checking the fuse
