Ok, this is my first post on here, so hello to everyone.

So I have a 99' Audi A4 that I bought a couple weeks ago. It came without a radio, so I ordered a wire harness and bought a radio. This is not my first time wiring an aftermarket radio either. Anyway, I wired everything up, but long story short, the BLACK and RED wires (ground and power) wires touched! Uh-oh. The power on the radio went out. I also noticed that the blower stopped working. And my radio is really cheap and doesn't have a fuse at the back of it, so that isn't the problem.

I checked the radio and blower fuses, so I really don't think that is the problem. What else could it be?
