Hi everyone I have a 2000 camaro and I am having problems with the turn signals. It turns out there wasn't a relay in there when I bought it. I put in a new relay and I try start the engine and it takes a while to crank almost as if I would need a new battery. Every time I try to start the car the fuse burns out and the turn signals don't work. Do I have a wiring/electrical problem? Any ideas on how to fix it? Thank you
