I have a 1995 F150 XLT, I love this truck so much but an annoying issue just popped up. Turn signals randomly stopped working, so I replaced the bulbs the fuse and the multifunction switch which I figured needed replacing anyways after 30 years. Still no turn signals! Leads me to believe it’s a wiring issue which I have no idea where to start or what to do about. Anybody have any ideas? Local ford service center will charge me a $180 just to diagnose the problem and if I can figure out a fix in my own I’d much prefer that, and the knowledge. Thanks in advance!

 

Welcome to the forum. Flasher unit perhaps? You didn't mention motor so I just picked 5.0...

Do your hazards work? My old 240sx had the turn signals stop working and it was due to a faulty hazard switch. Grab a multimeter and check to see if that flasher is getting powered when you turn the signal on.

 

Do your brake lights work? If no, then could be a grounding problem.

 

I have replaced the flasher relays and the brakes and hazards work just fine. If it’s a grounding issue what would I do to fix that? Really trying to avoid taking it to a mechanic if I can

 

Check the health of the ground connections at the kick panels. Those are know to rust to hell and cause issues.
