Ok... I guess it wasn't a short circuit and possibly the radio itself.. I put the factory radio back in the car and it's working fine.. I checked the fuse on the radio and it looks fine.. I'm going to try to change the fuse even tho it looks ok as someone suggested.. I don't know what else it can be???

I'm going to bring the car to a mechanic to fix the air conditioner.. I'm not trying to mess around and mess something up..
