I can't seem to figure out a problem that just started with my right blinker on my 2006 F250 6.0. When I turn the blinker on all the way it does a rapid flash and the bulb in the front does not light up but the one in the rear lights and rapid flashes.

I replaced the right front bulb and it did not fix the problem. (the old bulb looked good)

I swithched the relays (right with left) in the fuze box under the hood and nothing changed.

I checked all the turn signal fuzes and all seemed to be fine.

Can anyone advise me as to what to try. Thanks in advance.

Sounds like the issue is w/ the wiring or connector to the right front bulb.

 

change the blinker fluid! JK yea what bismic said

 

The right front bulb flashes when I turn on the EM Flashers so I know the connector to the bulb is good. This does not sound good if there is a problem hidden somewhere in the wiring. Thanks for the help anyway.

 

DentalDave:

Try your right turn signal WITH and WITHOUT your parking lights on.

There is a "front side marker" light that also blinks,
but opposite to the "front turn signal".

It could be the problem with the turn signal is the side marker bulb.
With the 4-way (emergency) it's not effected by a missing bulb.
Also check your side marker with the 4-ways going.

 

Thanks Misky6.0, I will check this when I get home.
Also thanks for not suggesting the "blinker fluid" solution!

 

Was that intended to be a pun?

Let us know, electrical things are always weird.
But, "most" of the time they are obvious - once you figure it out.

 

I finally checked that side bulb... it is good.
The right mirror has a blinker within it as well and that is currently broken... Would that cause the rapid blink? I can't exactly remember but I think the mirror was broke before this became a problem.
I am afraid this might be one of those mysterirous electrical problems never to be solved.

 

Me thinks that if ANY bulb in the blinker system is non-functional, it will affect the blink rate as it changed the load on the electronics.
