Electrical Gremlins

Has anyone had issues with the turn signals, or the Sync system just going blank? My turn signals work, but they flash quicker than usual and my Sync screen went blank one time. I would hate to take it in for an expensive repair when it maybe just a fuse. Any thoughts?

Hyper flash in the turn signal means you have a bulb out usually.

Thanks for your input. I thought the same thing, but all the bulbs work. I will check them again in case I missed something. The dealer also looked at it and said he had to have an electrical guy look at it, and I would have to leave it there for a week. Ummmm...thanks, but no.

I would turn on your flashers and walk around. See if any aren’t functioning correctly. That’s my best guess. Sorry if it isn’t more help.

This happens when a light burns out. You say that all the lights are working? So my guess is that either one is about to go, or you have a poor connection (dirty light socket) likely the latter.
Four solutions...
Remove all the bulbs, clean sockets with electrical parts cleaner and install bulbs with dielectric grease
Replace all the bulbs with new LED bulbs
Try and replace the flasher https://www.autozone.com/electrical-and-lighting/turn-signal-flasher/ford/f150
Or turn off hyperflash with forscan

Thanks to both of you. I'll do that.
