I have a 2007 f250 6.0 and I'm having problems wheneverI turn on my right turn signal there is no green arrow on the dash display and I hear the sped up clicking noise that comes with a bad bulb. The rear bulb is in working order still, but the front one and the mirror light do not come on.

Where I'm having trouble though is that when I lock the truck or use the hazards both of those lights (turn signal, mirror) come on just fine. So does anybody have an idea of what could be causing the turn signal not to work, but the light to work for everything else?

 

You MUST EXPLICITLY identify what you are working on, we do not have a crystal ball.


Odds are you have a MFS issue, but we can't research anything since you didn't tell us what you're working on.

 

Sorry about that, didn't realize that I didn't. I updated the original post with clearer information

 

That would be an internal failure of the multi-function switch. Nothing else can cause that particular set of symptoms.

 

Yep that was it, just replaced it a little bit ago and works perfectly again. Thanks for the tip, that didn't even seem to cross my mind until you mentioned it.
