So I just got it out of the shop today. New engine and it runs great. break lights work headlights work high beams work, but my turn signals aren't working. When I turn on a turn signal It makes that break light not work as in (left turn signal on, left break light doesn't work) now I know/have heard that's because they share the same light. I checked the front lights they don't blink either. I bought a brand new flasher cylinoid, or relay and nothing changed. Is there fuses for the turn signals?
There is a bad ground someplace. Can happen just from sitting over winter. I have even seen the contact become poor between the bulb socket and lamp housing. It is a press fit and the contact surfaces can corrode between the 2 stampings. A little corrosion between mated metal surfaces can play havoc with the turn signals.
