The fuse was blown and has been replaced, but it keeps blowing. I have done nothing electrical with the car since I put the head unit in almost a year ago. I searched and found nothing about this.

I am good at the mechanical parts but not so good with the electrical parts. Any help would be appreciated.

 

it might be a power wire grounding out. that will cause a fuse to pop. might have to follow the wires and see if you have a kink in the protective coating. I had that happen to me. a power wire was pinched, and was grounding out.

 

same here man i had my power wire pinched where the rear right tail light assey was at

 

ok so I fixed it today. Here's what was going on...
Fuse #8 was blowing. That is basically everything that comes on when you put your headlight switch in position 1. I looked over the whole car and finally found the wire from the dimmer switch to the radio was just hanging there grounding out. So word to the wise... look behind the radio first if you have an aftermarket unit.
