did u try changing the fuses out?.. my car had some cheapass fuse in the rear defroster spot… it didnt actualy break… it cracked only on one side so the power couldnt get accross but u couldnt notice it by just pulling it out… mine fell on the ground when i was looking in the hole to see if the last owner got wire or somethin stuck in that fuse hole… and when it hit the ground it broke completely
look inside the fuse holes… see if the metal is still there… on my uncles mustang it popped out somehow and there was nothin for the flasher to connect too anymore
Can you smell burnt rubber? Let’s hope that it wasn’t your wires that got fried. It happened to me before (in a different car) and what I ended up doing was rewiring my turn signals. Good luck.
