Maybe a turn signal fuse or relay problem?? - 2003-04 Mach 1 Registry Owners Club

Ok so my girlfriends 2007 Mustang is having turn signal issues.

Her rear passenger side turn signal does not display the furthest light (there are three lights). However, when I turn the car lights on, that same bulb has no problem turning on. No issues with the same bulb when I turn the emergency flashers on.

So I checked the owners manual in the fuse section to try to figure out which fuse is the turn signal... It does not state one. Does anyone know if the turn signal fuse is the issue?? If so, where is it located as I pull off both fuse boxes and none of them have a description...
Thanks for any help

Don`t know for sure but the bulb could have two filamints in it. One for the turn signal and the other for the running light If your flasher in the car runs really fast when you put it on right turn it`s the bulb

Your saying the tail light/ brake lights work but that same bulb doesnt work as a turn signal?

change the bulb first.
