Please help my 84 k5 has lost it's turn signals.I have checked the obvious fuses,turn signal (relay ?) that plugs into the fuse box.I'm not sure where to look next.It has that turn signal switch with the wipers,cruise control ect. on it. I don't know if it makes a difference but my 4 ways do work. I'm tired of using hand signals,because i don't think people know what they are nowdays.
