Changed the fuse 3 times in one day. It keeps blowing and Im' not sure what is wrong.

 

It's probably blowing because there is a short somewhere in the wiring.

Are you using the cigarette plug to power something? A phone charger or radar detector? If so, I would look for a fault in those chargers. If not, you need to trace the wiring and see where the short could be.

The fuse is doing its job, protecting the circuit from too much power.

How long has it been doing this?
Did you install the proper (25amp IIRC) fuse in the proper location? (fuse box behind the battery in the trunk/boot on my 308)

There was a car charger in there, but i noticed it wasnt charging, so I swapped out the 25 amp fuse 3 times and it immediately blows with nothing plugged in.

 

Sounds like a short -- I thought the only thing powered by that fuse is the outlet, so it might be fairly easy to find the short. I'd suggest pulling the outlet and check the wiring.

I'd also check the wiring diagram to see what else might be powered through that fuse and check those (if any).

 

Might look down into the socket to see if anything fell into it.

 

Yea, I found a US penny in mine when I bought the car, they fit perfectly!
