I was installing a deck in my girlfriends car(1994 toyota corolla) and when i wired it up the deck didn't work and I returned it and goto another one, but this isn't working either so its for sure the car. I am getting power because the red wire touched the metal by accident and sparked. It blew a fuse and I replaced but I'm still getting nothing. Also now the turn signals don't work. Any ideas on whats wrong with the deck install and the turn signals. P.s. I know i wired the harness right.
