Ok, so I'm driving down the road and my radio RANDOMLY stops working...?
The dome lights go out...?
AAAAAND the electric lock doesn't work inside the car, or on my key chain one (and the battery is completely fine, we checked that)
It was so random...So the lights, the radio, and the locks.

I was looking on Google and someone had the same problem with their Jeep Cherokee, so I checked it and it was a light blue fuse under the hood.
I looked under my hood and there is a light blue fuse, but it's like..a fatt one? Or like two conected? I don't know, someone pleaaaaaaaaaase help me out!

If you could help me out, and give me an estimate of about how much it is going to be to fix tihs? Thanksss!
