2005 F250 Blinker Problem

I have a 2005 5.4L F250 with a blinker problem. When the passenger side turn signal lever is held up half way the blinkers work fine. When the lever is pushed up all the way only the rear blinker flashes and it blinks very rapidly. Any ideas?

Sorta sounds like the turn signal switch, although I cannot explain the fast blink. Anyway, I'll bump this for ya.

I had the same problem with my blinkers on my 99 SD and it was because I put LED light bulbs in the taillight I guess it didn't draw enough current. Replaced them w/ regular bulbs and they worked fine. Just make sure the correct bulb is installed. Did it just start doing it or has it done it since you owned the truck?

Sounds like your multifunction switch needs replacing.

............or maybe your blinker fluid is low?

It just started doing it on Saturday night. I have the original bulbs in it still.
